Title: Ground Station
Post by: EricC on May 26, 2016, 05:32:50 pm
Just received my PilotAware Bridge, now up and running.

I am located 1 mile south of Poulton  Railway Station
N.N.E of Blackpool Airport.  Point 52 on the map

The Bridge Aerial is located on my house roof if
anyone is  flying by feel free to use for range checking etc.

Contact me on 07905336066 to check it is switched on.

Assuming I get my ground station up and running today, what are the best settings to identify it?

Do I just make up a Reg?
Did a GroundStation setting get implemented in the software?
Title: Re: Ground Station
Post by: exfirepro on June 10, 2016, 09:40:50 am
Hi Jeremy,

There is a setting in (Configure) (Aircraft Type) for 'Base Station', which transmits this information as part of the P3i data. Some Nav Systems can apparently display this, but I don't know which ones.

You 'can' put something other than your 'Reg' in the Flight ID box to identify yourself. It has 12 character spaces so 'Jeremy Base' for example is possible.

(Page 27 of the new Operational Manual refers)

Peter

Righto things are kind of up and running, bit of a mashup at the moment but functional.  Had some alerts from a tiger moth and an R22 flitting around Cambridge, according to the radio traffic anyway.

If anyone is around Cambridge way I will try and have it on most of the time, I'm inside the EGSC ATZ to the North.

I've been on the map for ages down as 'JCurtis'  ;)

As for my base station name, I'll see if anyone spots me, I've left the group as default so it will have the #'s around. 
There could be a discount code for a charger available for the first correctly reported spot ;D.  I'll leave it on as much as possible during the day, if the weather is bad it might go off as I've not weather protected it at all yet.

To the one member on here who I let know what it was set to, you are not eligible to enter!

Remembered to take a screen shot before shutting down for the day, no-one been down my way yet it seems.
Won't be up tomorrow but expect to be running Tue/Wed all day.

Yesterday I had the PilotAware connected via some test gear monitoring the power draw, over the day it took 58.14m readings and there was quite a span in terms of consumption.  The minimum was 0.658A with the max being 1.326A, this was with the PilotAware unit, an iPad connected running SkyDemon and I guess an average of circa 55 ADS-B/Mode S targets shown on the traffic page when I looked from time to time.  Voice alerting also running via a set if ear bud headphones.  The unit and iPad were powered by a Charge4.

Hi Eric,

You can download the track logs onto a laptop, PC or Mac via the 192.168.1.1 wifi address and they can be opened and read using 'Notepad' or 'Wordpad'. Takes a bit of getting your head round though at first. If you are struggling, drop a note to Lee, he has a programme to analyse the logs - just don't everybody ask at once or development will grind to a halt  :)

Let me know how you get on

Title: Re: Ground Station
Post by: Admin on June 13, 2016, 09:22:18 am
How can you tell which ones are P3i and which ones are ADS-B?

There is no definitive way from this file TBH, but assuming that the receiver has not changed its default 'Group-ID', and the transmitter has not changed its default 'Group-ID' - so both set to PAWGRP, then any PilotAware Flight-ID will be bracketed in '#'

eg,
$PFLAA,0,14163,14666,29,1,405CA6!#G-PAW4#,58,,48,,8*7B

I thought of that but out of supposedly 122 P3i messages in the file I sent you, I did a search for "#" and couldn't find any. My PAW still has PAWGRP as the group default.
Title: Re: Ground Station
Post by: Admin on June 13, 2016, 11:38:53 am
If we are going to have ground stations, I think it is worth the investment of having a higher gain antenna.
You really need good clearance based upon your surroundings.
The ground stations we used during testing, were in the middle of an airfield, and hence were completely void of obstructions
Keith is experimenting at the moment with a collinear type antenna, to see what kind of results that would give for a ground station.

Post by: Paul_Sengupta on June 13, 2016, 11:56:09 am
Is that a collinear for the ADS-B or P3i? I already have a collinear which I made for ADS-B, but a P3i one would be good for a ground station as well. It has the added complexity of the transmitter and VSWR matching as well though if the unit's going to be transmitting.

I've currently got my PAW on my upstairs windowsill with the ADS-B antenna unplugged so I only get P3i!  :D

Well I would if anyone was flying.

Apologies to anyone kept low by Farnborough overflying Guildford and getting a traffic alert from G-DOGG!  :o ;D

Ground station antenna. Vertical 1/4 wave home made.

More than happy to try out another type is if it is any help.

I have fitted mine to the ridge tile on the house roof.
The only screening is to the west, chimney stack.

Title: Re: Ground Station
Post by: Admin on June 13, 2016, 10:07:41 pm
Hi Eric,
Please don't be concerned, I think it is fine to keep this up and running, this is not going to cause an issue right now.
As I mentioned earlier, I will have the base station disabled from transmission in the next release,
so will not be a problem, should a number of base stations pop up.

I have a question, do you have your basestation connected to the internet through your router, or simply stand alone.
It would be pretty easy to automate uploading of received data to a server - in the same way the automatic updates are downloaded.
This would mean you would not need to post your data manually, we could collect automatically.

Thx
Lee

How about having a network of ground stations feeding into FR24...?

It would be easier if the Wifi could be configured to connect to the home network rather than having to use a cable.
Title: Re: Ground Station
Post by: Richard W on June 14, 2016, 01:38:03 am
Please could we have the option of transmitting from a base station, if required? Or maybe two sorts of base station, tx and non-tx? At the moment they are very useful for testing airpborne PAWs.

To wifi your Pilotaware to your network you simply need a wifi extender, something like the bt one, or one from maplins, there are lots to chose from. Plug your Pilotaware into the wifi extender via the network output rj45  and you now have it connected wifi. You can remove the wifi dongale from the Pilotaware as You now conected via wifi network. It works a treat.
Title: Re: Ground Station
Post by: Paul_Sengupta on June 14, 2016, 08:56:45 am
It would be easier and take less electricity if it were to be done within the PAW.

As for base stations transmitting for test purposes, surely you just need to set it to some sort of aircraft instead, rather than setting it to "base station" for that to happen? You can still set what ID you want it to transmit.

Post by: Richard on June 14, 2016, 10:23:15 am
My concern for an explosion in Base station was that anyone can buy a PAW, non flyers, and wannabe's and genuine aviation people. I'm all for the base station set up correctly, Some one at sherburn suggested trying to set up an on screen Radar (Flight Radar 24) for every one to see in the club to monitor traffic around the airfield..... I suggested to them it would be far better to use PAW for very accurate results, We may have an uptake from the suggestion too!
Title: Re: Ground Station
Post by: Deker on June 14, 2016, 11:11:13 am
Can there be an option in the config screen so that we can choose to display ground stations or not, rather than kill the option altogether?
Best of both words:-
Disable the display of ground stn' if you're flying and don't want clutter.
Enable ground stn' display when testing.

I have used a PAW on the ground and watched people doing circuits. I've also used a PAW on the ground to watch someone fly over to the training area near Diss/Eye and fly around there, training!

My school are thinking of fitting them so they can watch their aircraft from the club house.

I'm either having a Brain Wave or a Brain Fart.

If we want ground stations why are we going down the route of Pi's and Bridges? Isn't a SDR dongle capable of receiving P3i transmissions? It could then run on a Pi or a PC. I know someone will have to write the software, or adapt what is already out there? but it would be cheaper and it would make integration with Flight Radar 24 (other software is available) much easier.

Regarding the term Base Station/ Ground station maybe an option
would be the term (Test Station) indicating that it is for range test purposes.

Authorised by PilotAware to be used as such.

Lee, does a ground station, that is transmitting appear as an alert to passing aircraft? Could cause some confusion as reported on the Flyer forum. Obviously ground obstruction should alert an aircraft, but monitoring/testing should be suppressed in some way? Monitoring could have the TX turned off as mentioned elsewhere, but testing?

Obviously ground obstruction should alert an aircraft, but monitoring/testing should be suppressed in some way? Monitoring could have the TX turned off as mentioned elsewhere, but testing?

I only control the audio alerts, and this will raise an audio alert which is based upon proximity.

I dont think SD will complain as it does some analysis on trajectory and proximity.
Also for the navigation devices the ground station will appear as static, it will not have an extended track line.

In the next release, I will add the ability to ignore ground stations if desired, this means they can continue to collect and supply data, if desired.

Well if my trig is right, then I was picking the first at a range of 20.6km to 23.6km and the second starting at 13km, closing to 7.8km, then increasing again to 12.9km

I've not looked at the log in detail, but if the lat., lon. and alt can be stripped out you should be able to parse it for Google Earth?

I used to do a lot of this stuff, but have been out of programming for a few years now.

Well what I have is the Easting and Northing relative to me, so some basic trig to get the relative bearing and distance.  Once I have that I can then work out the lat long based from my own fixed position, throw in the relative height, and generate a file.  I remember doing this stuff in ground school, amazed I could remember it to be honest!

I suppose I could just cut the corner and convert everything directly into Lat/Long...

Which log Interface messages have you got enabled to see PAW packets?

I spotted a number of RX packets on TXRX section of the home page, so went to ListTracks and downloaded the track for the day (all 57Mb of it).

Then I cheated a little and just hoovered the lines with '#' in them to make things easier, on the assumption that the passing aircraft was still using the default groupID of PAWGRP.  If they are using a different group it's not easily possible currently to pick out PAW aircraft.

cat /Users/JCurtis/Downloads/2016-07-03_07-03.trk | grep "#" > /Users/JCurtis/Downloads/2016-07-03_07-03_strip.trk

In these log files are the $PFLAA messages, these provide relative data for displaying on a device.  I have masked the callsign I picked up...

$PFLAA,0,-5251,11794,854,1,406E85!#     #,82,,40,,8*7F

Found my first 15 Rx packets today with the PilotAware running as a ground station, no sign of any PAWGRP groupID in the 33mb file though unfortunately. Anyone noticed a ground station 7NM NW of Netherthorpe?

Thanks Jeremy, I now understand why you are having to take extra steps to extract the data. if you enable trx logging, you can clearly see the PAW traffic in the diagnostic log file complete with Lon, Lat of the other aircraft.

I could do that, but I leave it unattended 99% of the time and I just check it from time to time.  I have seen one of the aircraft seen earlier do a reverse journey a little while ago and took a screen shot or two from SkyDemon, to compare a computed track against a real one.

If you turn that logging on does it get written to a file too?

I need to create some extra networks on the LAN here for a project I'm working on, so I will make the effort and put PAW on it's own VLAN so I can leave the ethernet connected and still use SkyDemon with it on the normal network too.

They are plain text files, so you can just rename them to a .txt extension and open them in a text editor or .csv for Excel. Note they can be large!

Another visitor passed by today, call sign was a little odd but after a quick search it seems this it was the Flight ID of a twin that passed by Cambridge on it's way out and back on a trip to the SE.  Held onto that one until it was 16.4km away.

What is your secret ? Are you using the same antenna that was supplied with the ARF or have you some elevated high gain setup.....I'm only picking up contacts for about 2-3km using my ground based kit

Using the antenna that came with the PilotAware for P3i but on a 5m extension cable, it's sitting on the roof of my office along with a higher gain ADS-B antenna (no pre-amp).  The ADS-B will pickup up to around 230Km.  The height of those I have seen has been around 2000'-3000' but I haven't taken the slope angle into the distance calculations.  The office roof is metal clad that could well be helping, but they are sat on the edge for easy recovery.

Overall site elevation is around 50 feet, essentially the same as Cambridge AirPort.

I have only seen three 'targets' I could identify from the logs and no idea if they saw me, no-one has been in touch with my base station name to claim the discount code on a charger as yet.

It's a pretty crude install, and not weather proof as yet (i.e. I bring it in when it rains), still working out how best to get the various antenna mounted and weather sealed.  I have a few in addition to the PAW ones to mount at some point.  I'd post a pic but it people may laugh!

All run from a Charge4 that I use to charge things in the office rather than have a bunch of PSU's knocking around.

Thanks for that.....the P3i antenna I presume is the same kind of build as the old ARF one in so much as that its a staged dipole constructed in a single ABS sleeve....Lee mentioned that he did tests with a sportcruiser using a monopole and utilising the ground of the airframe.....I wonder if that is a better way to go beefing up the groundplane

Yes I suspect internally that is what is it, I haven't popped it open to take a look.  I could try an ARF one, I have a few knocking around, but without knowing who or what may be passing I have no way to judge what is what.

The antenna are not connected to the ground plane, just sat on top of the roof on a bit of 4x2, but having a ~11m/sq of metal underneath will be doing something...

I really must get something better sorted out  :-[

They are in theory the same, but we found that the ones we had specifically made for PilotAware are in fact better tuned. We tested them side by side in the same aircraft on test flights and although we got 20nm from the old antenna, we actually saw even more from the one supplied in the kit and on the hardware website.

Still.. 20nm should be plenty !

Better watch out Jeremy, he's after your discount!!  ;D

Seriously though Brinsley, I'm not particularly surprised you weren't getting many P3i contacts en route to Sywell. I can't believe the number of fellow aviators who haven't even heard of PilotAware - let alone got one. We seriously need to spread the word and get our colleagues to buy in to the project.

Only 2-3 km from a ground station, however, definitely sounds like something isn't right. Hope you get to the bottom of it.

Hi Eric,

A Grob Tutor (from G-INFO). Squawking Mode S at 6,500 feet QNH. From the signal strength, it looks like it went straight through your overhead, or certainly very close - hence the Mode S Danger Alert on your Nav Screen. I seem to remember you are now full Pi2 with Bridge, so you will also have got the full PAW Audio Warnings as it went through - though you may not of course have been present. I take it you have your Mode S separation set at quite a high level? Out of interest, what 'Mode S Detect Range' did you have set?

Regards

I'm also leaving my PAW running as a ground station at the moment when not flying.
It's situated SG19 2LF approx 3 miles East of Sandy.
It's been running 16 days continuous now have RX=502.
Just positioned by a window facing west.
If you want to swing by Brinzlee :)

Config screen as attachment.
Grob about 4 miles to the east.
Visual to me tracking north/south for about 15 mins.

I have been studying the Sig levels that trigger warnings, all seem
very well set.

The warnings on xcsoar always show the target overhead as no lat long data transmitted
by mode S guess no extended squitter fitted on these aircraft.

Running a Pi2.

Hi BNMONT

That's very interesting as I flew over Sandy last Friday enroute to the Sywell Expo. That's one big mast you have there !!....I was at 1500 feet at about 12.15BST......I didn't get any contact if you've had your base station on for the past 2 weeks....Again all very odd....!! Registration G-MASS
Title: Re: Ground Station
Post by: exfirepro on July 05, 2016, 10:53:14 pm
Hi Eric,

The Grob was definitely straight Mode S.

Extended Squitter (ADSB) would have shown the distance between you both - based on your relative GPS positions - in the 'DIST-KM' column of the traffic table - as EI-EKN on the top line. The rest on your table are all 'Mode S'.

I'm just slightly surprised to see a signal strength over 200 at 4 miles, but then again if it was clear line of sight and I seem to remember you saying that you have your antenna up on your roof ridge in the clear. It is of course possible that that particular Grob is fitted with a higher power transponder, which could put out up to 250 Watts, rather than the 'normal' GA type which generates about 125 Watts. This is the essence of the difficulty in trying to establish effective alert 'distances' from bearingless targets (i.e. raw transponders).

Regards once again

Sorry Peter, not strictly true.
G-GDFF is definitely ADSB as I've just tracked him in the air right now, & as  EJM11 is displaying the full SIL & SDA data he must also be ADSB and I'd be extremely surprised if the other Ryanair, EI-EKW, wasn't ADSB too.
Strange but true.

The Grob was flying a race track pattern, the Sig 202 was the highest

The Bridge aerial is on the roof, adsb on the Paw in the loft space 1/4 wave
with ground plane.

Typical, go to drop off some orders and someone does a fly-by.

OK Alan, point taken, so I'm a bit confused now. My comments to Eric were based on the results shown in his traffic table. As you are aware, HEX + SQuawk + ALT  + SIGnal strength - with no DISTance is the known signature of a Mode S transmission (we've looked at plenty!!) - no horizontal position information, so PilotAware can't calculate its distance from your receiver.

So what Eric seems to have been seeing is a combination of clear ADSB (EI-EKN), clear Mode S (The Grob G-CGKS) and what appear to be Mode S responses from what you have clearly observed to be ADSB equipped aircraft - namely G-GDFF and EMJ11 (sorry Eric I overlooked the significance of the SIL /SDA entries in the case of EMJ11, but couldn't have known about G-GDFF - at least not without looking it up on FR24 or G-INFO).

Eric, I'm wondering - was it raining at yours at the time? You say your 1090MHz antenna is a 1/4 wave with ground plane inside your loft. Heavy rain or snow on the outside of a slate or tiled roof is a known cause of significant attenuation of radio signals at this sort of frequency. I'm beginning to think this might account for only the high power 'pulsed' CAT Mode S return from these CAT ADSB transponders being strong enough to 'punch' through the wet roof to your antenna, and hence the lack of an ADSB based positional DISTance in the table. Best explanation I can think of at the moment anyway. Anyone else got any ideas?

Regards

Peter

Hi again Eric,

Not too bothered about the Grob, I'm quite happy that was Mode S - as I say, the signal strength fits with an aircraft using a higher power transponder (such as a Trig TT22 or similar) - which outputs up to 250 Watts as opposed to my TT21,s 125 Watt maximum.

The problem is the entries that Alan is saying are definitely ADSB equipped aircraft, so should be showing a DISTance from you in your traffic table. One thought was attenuation from a wet roof, but you say the roof wasn't wet - I take it it's not made of, or lined with metal (e.g. aluminium foil on insulated plasterboard)?

Another thought was that you are very near Blackpool and quite close to Wharton. When CAT is on the ground, the ground radar returns are effectively mode S at very high power, and show up as such on the PAW traffic screen. During testing near Edinburgh Airport, we noticed these were often strong enough to trigger Mode S 'Danger' alerts from well over a mile away, which is why we developed the Ultra Short Range setting specifically to deal with this type of scenario. I also noticed that some of them don't engage ADSB until well into the climbout, which might have explained aircraft less than say 2,000ft, but not at the heights yours are showing at, so doesn't help to explain those.

I will give it some more thought.

Regards

Peter

From my Kinetic SBS1 base station only about half of the returns are ADSB
Comparing the logs as near as i can tell they are the same as the PAW.
Title: Re: Ground Station
Post by: exfirepro on July 07, 2016, 10:36:22 am
Yes Eric,

PAW and ADSB both show in a similar manner on the PAW traffic screen, though PAW, being much less powerful transmitters, generally don't have a significant SIGnal strength. Also the SQuawk for a PAW transmission will be the group-ID (e.g. the default 'PAWGRP' or whatever the user has set) as PAW doesn't transmit a conventional squawk.

That's why I had no concerns with my original statement - until Alan picked me up on it  ??? And let's not forget all those out there who either haven't bought or can't afford a transponder - or have one but fly with it switched off. That's what makes PAW with its definite gps-based location info such a bonus!

I did have one contact from a ground contact at Old Buckenham but we were on the ground too right next to him with a rather poor range of 500 metres before I lost contact when I took off......
I have tried lots of options now....the aircraft was composite this time so I can't even blame my poor range on metal cladding which is what I thought was restricting my TX/RX. Tried a variety of Antennas.....Fully charged batteries.....Heavy duty power leads.....

Well if you were in G-OAWM I was seeing you, lost you at 7.6km. 
I know I TX something as I pickup the RF on a spectrum analyser.

I think you were literally almost overhead at one point, I could have stood outside and waved.

If this was you, could a potential local source of interference could be swamping the Bridge RX perhaps?

Post by: exfirepro on July 07, 2016, 06:54:32 pm
Definitely something strange going on Brinsley. Alan and I have been getting 5- 10 miles reliably with pretty much  standard kit. You will get some screening forward left and down from your engine with the P3i antenna in that position, but should have 'seen' Jeremy well before the point where that might have become an issue.

Assuming you were in G-OAWM and he saw you at up to 7.6km, you are certainly transmitting. A bit surprised that you lost your old Bucks contact at 500 metres too - definitely sounds like a receiver issue to me.

Hi Brian,
Unless you get a good line of sight - you will not get any transmission propagation at these frequencies, this is why TV Aerials go on top of roofs  ;)
I can get about 0.5km in a built up area where there are lots of buildings, radio waves at this frequency have no penetration whatsoever - you canny change the laws of physics cap'n
luckily, for the intended use of PilotAware - we get pretty good Line of Sight  ;D

Well it wasn't on at 6am, it was at 5.40pm but as Lee says I doubt you would pick me up.  There is quite a bit between the A14 and me, my elevation is only about 50' and I believe the A14 is lower in a cutting as is passes North of Cambridge.

The nearest VRP for me is the A14/A10 junction, but that is about 1/3 of a mile away.  No good on the ground but fine for in the air.  You'll have to come by whilst airborne.

the Air-Air protocol contains Lat/Lon/Alt/GS - this is what would be passed back to a central server.

Hi David
I returned my Bridge to the normal address in Ely on Friday and have noted it wasn't delivered by the Post Office on Saturday.....Just wondered if you had received it as I'm not sure where it is now. They said they have put a card through the door...Perhaps you can enlighten me

Picked up someone today, 75 packets, nothing in the log file with a # on it.

A slight aside, the track viewer doesn't seem to work on track files since the last software update, can someone else check if theirs works OK?
Title: Re: Ground Station
Post by: brinzlee on July 15, 2016, 12:29:36 am
Mine doesn't work either.....I did a manual search for anything with a # in the original TRK file with a text editor. Copied and pasted just those entries then Saved it as a text file, renamed it as TRK file then read it back into the track viewer and that seemed to work

Well there won't be any #'s unless they are set to the default group (PAWGRP).  Nothing today.

So if the PAWGRP has been changed that removes the # around the registration.....Is there any other way to then test the TRK file for a P3i transmission

I got one too. My furthest to date....9.4km. Three flying in formation through the Southend overhead one PAW equipped. I think there must have been a flyin on the south coast some where as they were all the same type of aircraft. I noticed one earlier on in the morning full ADSB out.

The second Initially 11.6Km, then a close pass 0.7km, finally disappearing at 8km.  I think the last pass someone PM'd be about to check if the base station would be up.  Will someone come forward with my base station name and claim a discount on a charger?

Hi Lee

Really getting into the TRK breakdowns....furthest return today was 23km....So I guess that confirms there must have been some sort of issue with the previous Bridge..

Anyway I was following a flight just now and I know the owner of the PAW but was wondering what he has done in his setup as it was returning two sets of data....Pictures enclosed if that makes sense.....I have noticed a few other aircraft PAW equipped doing the same thing. The entries are in green at the top of the traffic table. First it reported it as GNULA then a hex code on the SkyDemon. Has he got the wrong transponder hex code in the PAW


Thanks for all your previous help with the Bridge.....as always a complete star !!

Kind regards

Brinsley
Title: Re: Ground Station
Post by: Admin on July 23, 2016, 07:47:53 pm
Hi Brinzlee

It looks like he is ADSB and P3I equipped, BUT, using different ICAO codes
In fact, his transponder is set as 123456, which is most definitely wrong.
As far as I am aware, all uk codes are allocated as 4xxxxx.
This would explain 2 aircraft shown, I presume the PAW code is correct as it
Begins with a 4

Thx
Lee
Title: Re: Ground Station
Post by: exfirepro on July 23, 2016, 11:08:35 pm
Hi Brinz,

4A276F isn't the right Hex code for G-NULA either.... and if as per G-INFO the aircraft is a CT2K microlight, I don't think the CAA would be amused at it squittering ADSB with the wrong ICAO code and a SDA level of 3. If you know the guy, perhaps a discrete word about his transponder / ADSB and PAW settings might be appreciated. Unless of course there is something else very strange going on.

Regards

Peter

Title: Re: Ground Station

Thanks.
Title: Re: Ground Station
Post by: exfirepro on August 02, 2016, 07:12:48 pm
What kind of information are you looking for Eric?

I'm guessing you already know about ADSB - up to well over 100 miles depending on your location and antenna position.

Mode S - depends on what range setting you have selected in (Config), but I have seen well over 50 miles in 'Testing' though couldn't run in that setting for long without unplugging the audio.

P3i up to 26 Kilometres in clear line of sight, but P3i is easily attenuated by buildings, aircraft body construction and big bags of water (aka - People). Unfortunately, operating from the ground you are likely to feel the effects of this more than if up in the air and need to optimise your receive antenna type and position. In practice, I have found P3i consistently reliable at up to around 10 miles - which is far further than any of us can see, but this can be subject to the vagaries of individual installations.

Keep up the good work.

Regards

Peter

Title: Re: Ground Station

The distance from the ground  to aircraft.

The P3i Tx aerial is outside on house roof with a clear view of the sky
so be interesting  how far away it has been received.

Mode S and ADSB are no problem.

Saw about 8 - 10 PAW contacts with one of then at 47Kms (we need to check this as it seems too good to be true even with my set up. Anyone out there transmitting 470265 in the Hex and Reg fields??).
So definitely a lot more out there to see.
Quite a few round Milson, Telford, Wolverhampton, Pound Green.

Getting more out there its working.

I guess the days are getting shorter and colder, so I would expect flying activity to go down, but nothing in 20 days almost sounds like you are being avoided! Not deliberately I'm sure!

I'm starting to 'see' more PAW equipped aircraft during recent flights around the Lothians, so they are definitely spreading further afield now. Keep up the reports.

Hi Eric,

Activity levels are certainly getting up and pretty much reflecting the weather - as we would expect, though yesterday's total seems a bit low for such a good day. I flew from East Fortune over to Portmoak Gliding Centre and it was mobbed, with queues of gliders waiting to launch late morning. I was running my FlarmMouse integrated to my PAW, so saw loads of gliders aloft and when I was on final the PAW audio was going crazy. I flew back through the Edinburgh overhead to East Fortune and struggled to get parked for the number of our own and visiting aircraft (plus overspill cars) on the apron. A few PAW contacts on the way, but still far fewer than I would like to see for the number of aircraft out and about Guess we need to do a bit more advertising to get the message out to the World.

Regards

Peter

Post by: Ian Melville on June 13, 2017, 10:01:46 pm
Hi Eric,
Check the tablet is connected to the PAW WiFi
Out of the box, EasyVFR won't work, so I had to change one setting.
Go into EasyVFR Menu>settings and scroll down to FLARM/PilotAware settings
In there check that the Use FLARM button is green
Change the WiFly Pin-Code to 6000

Click OK
then back

You may see a brief message about an inaccurate position, but that should clear and traffic appears on the map.

Title: Re: Ground Station
Post by: exfirepro on October 28, 2017, 04:51:53 pm
Straightline,

In the early days of PilotAware, there were relatively few units operational. These were spread very thinly across the country and only operational when users were testing or flying. This made it extremely difficult for new users to find other units to test their new installations against, so a few individuals - like Eric - volunteered to set up ground stations so that new users could find a reliable local station in a known, fixed location.

Eric has been running his station from his house near Blackpool since May 2016 and likes to keep us updated with regular reports of local PilotAware activity. Transmitted (TX) data 'packets' indicate level of activity from his station since the unit was last rebooted. As this is reported on a (roughly) daily basis, we would expect 'Transmitted data' figures to be relatively consistent, but nonetheless this confirms that the station has continued transmitting reliably. Of more significant interest, when compared on a day to day basis over a longer term and taking into account the effects of varying weather on flying, the RX - (Received) data 'packets' from other PilotAwares give a direct indication of increasing levels of PilotAware activity in the local area which reflects the significantly increased take up of a PilotAware across the UK.

It is important to note that the number of 'packets' received does not directly reflect the number of aircraft recorded, though this could if required be determined from an analysis of the station log files.

Although perhaps of lesser importance these days for 'testing' of new installations as PilotAware usage spreads across the UK, these stations continue to be excellent test beds to demonstrate long term reliability of the equipment used in the PilotAware system.

Hope this helps

Regards

Peter

What‘s the use of publishing all these numbers? Should I (as normal PAW user) be interested in them (if yes, why) or is this kind of data base for an analysis for Lee and the team?

Not sure from the display ... think it just said” G Stn” , along with the difference between it and my height .. it was at Gransden Lodge, fairly close to Bourn airfield...

That’s what I remember it displaying on sky demon .. I think the radar display had an icon shown too

I have seen a few OGN relays ,.... only on the radar display on the second iPad in the top right corner ...
Title: Re: Ground Station

Yes, that will be an OGN station, so you would have been receiving data on FLARM equipped gliders as well. The will be annotated UP OGN rather than a call sign.

In English it means that one of the messages was not in the correct formator did not meet a quality check, so was discarded. Most likely it was corrupted by a another transmission 'Stepped on', or was to weak a signal.

From analysis I have done previously, this is due to a weak signal, so it tends to happen as the Aircraft is on the edge of good reception.

Hi Eric

You are a star for doing this over such a long time. Supporter of the month. :) :) :) :) :) :)
I was wondering if I could use this data to draw a graph to see how it had grown.

Would you have the space to fit an OGN-R station if w provided the bits. Then you would have a permanent and daily record of Gliders and PAW

Keith
Title: Re: Ground Station
Post by: exfirepro on July 01, 2018, 11:21:45 am
Good Call Keith,

I have been thinking of this for a while, but didn’t know whether Eric would be interested. It would also help fill a noticeable gap in the North West (of Engerland). Eric has certainly shown consistency and definitely gets MY award for ‘sticking with it’ 🥇. Well done Eric.

Regards

Peter
Title: Re: Ground Station
Post by: Moffrestorer on July 01, 2018, 11:24:16 am
Hi Keith,

Entirely agree with your sentiments!

Are you able to shed some light on how an OGN-R station can provide a permanent and daily record of PAW and glider traffic please? I was hoping that my station would provide this but the OGN-PAW:8082 browser page only seems to list traffic when it is actually being received i.e. doesn’t store the info unless I take a screenshot! What I would like is to be able to inspect a listing of traffic received and any “rebroadcast” of glider trajectory, at the end of the day, on a daily basis. Is this possible yet or am I going about it the wrong way?

Thx,

Chris
Title: Re: Ground Station
Post by: Admin on July 01, 2018, 11:38:10 am
Hi Chris

This is possible, would you just want a list of ID's ?

Thx
Lee
Title: Re: Ground Station
Post by: Moffrestorer on July 01, 2018, 12:08:41 pm
Hi Lee,

Yes, just a list of IDs and whether the glider/ PAW interaction triggered a Rebroadcast or how many rebroadcasts were made during any interaction. Pretty much like the existing page but data stored for later analysis, so you don’t have to keep looking at the screen and refreshing it because Firefox won’t Allow data updates. I guess date/ time would be useful as well. It’s really to confirm how effective your station is being, realistically, in providing a safety net.

Wouldn’t want to create lots of work for you or detract you from something more important!

Thx,

Chris

Regarding the ONG station,  yes  that will be good.

I will send a picture of the mast which the OGM  aerials can be installed.

Only connected to about 7Mbs download and 1.2Mbs upload, is this ok.

I will send a picture of the roof and mast, tomorrow.

Title: Re: Ground Station
Post by: Keithvinning on July 03, 2018, 04:42:05 pm
Hi Eric
Max length is about 10Metres. For the OGN you can actually us a USB extender.
If you put the pi in the Loft then 5 metres will be enough.
You need to put up 2 antennas though.
The internet is more than enough.
What is the antenna at the top not the YAGi

Prior to the internet, the antenna is question was for VHF Volmet WX.
l was able to check the WX from home before departing for Belfast in the C47 with the morning papers.

Checking on EasyVFR basic my ground station TX/RX symbol is an aeroplane.

Can I change this?

I have spoken to the helicopter pilot pleasure flying around Blackpool,
he confirmed my findings.

Hi Eric,

I don’t think you can change the symbols in EVFR. I think it’s programmed so that OGN-R ground stations show up as an antenna mast ( inverted Y ) but I think your ground station maybe is still a standard PAW traffic unit? That will show up as an aircraft! You could try asking Rob Weijers the question via the PocketFMS EVFR forum.

With Sky Demon, even the OGN stations show as aircraft as was highlighted on another thread; not sure about other Nav Apps?

Thanks for the info.  I am seriously considering  setting up a OGM station to resolve the situation.

Hi Eric,

The functionality of an OGN-R Ground Station is different from the standard PAW unit that you are currently operating as a ground station. It’s purpose is to provide an important safety facility to other PAW users who otherwise would not be able to “see” Flarm or OGN (broadly the same animal) targets as they transmit on a slightly different frequency from PAW. The alternative would be for all PAW users to integrate a Flarm Mouse into their systems which ain’t gonna happen given the cost of Flarm equipment.

With your present Ground Station you are able to produce the reception data that you post and view ADS-B and PAW targets on your tablet Nav screen or via the PAW Radar embedded in browser. Your station will appear as a static aircraft to anyone in range on their PAW.

With an OGN-R Rebroadcast Station the station collects relevant data (GPS position, speed, height, flight ID etc) from aircraft using the Flarm and rebroadcasts it real-time on the PAW frequency to any PAW aircraft within range. It also feeds data on both Flarm and PAW aircraft to the OGN servers via an internet connection, so you and others can see the aircraft data and tracks via glidertracker sites such as glidertracker.org etc. I believe that OGN also supply this data to third party apps such as FR24 etc. The system produces reception data on these contacts but in a more complex way as there is no home screen as you are used to with your PAW. The system doesn’t give you visibility of ADS- B contacts, but if these are of interest just view them via any flight tracking site such as FR24, ADS-B exchange or uk.flightaware.com

Regards,

Chris

Thanks to Moffrestorer for a detailed explanation regarding  the OGN.

If there is a gap in OGM in my area I am prepared to install one.

Hi Eric,

I wouldn’t imagine you would get an awful lot of ‘FLARM/OGN’ Traffic in your neck of the woods, but as I have said previously, you are in a good location to help extend the OGN-R network northwards, and you have more than demonstrated your ongoing commitment to PilotAware. If you haven’t yet done so, have a read at the installation / upgrade documentation in the OGN-R Section of the Forum here....

http://forum.pilotaware.com/index.php/board,9.0.html

...which will give you an idea what is involved. If you decide that you do want to come on board, I would be happy to pop down from Edinburgh and help you get things set up properly and I’m sure Keith would help with the necessary additional hardware. Drop me a PM via the Forum if you do want to go ahead.

Regards

Peter

The OGN-R  Station PWPOULTON has been live for approximately two weeks.
The PAW is now RX only.
I can reset toTX/RX if anyone wishes to carry out a PAW range/system checks.
If required call me on 07905336066.

Not sure it is wise to put a phone number in the post. A PM should be enough if people think 24hrs ahead?
