Technical Support / Re: Project: PAW Rosetta+Flarmbat+3D Printed Box

« on: September 25, 2020, 01:30:33 pm »

They are Dipol antennas omnidirectional, with two 90 degree "legs" and sma connectors. Advantage the signals are equal in all directions and still are fairly small (each leg is 10cm). They can be tuned to work at flarm or paw or ADSB frequency, but mostly used for Flarm in gliders to improve range.

Here is the website:
http://www.gliderdesignparts.de/ant_flarm.en.html

Just want to make clear that the superfants are not associated with PAW. I found them in a glider here in Germany and was curious. They work well in my set up.

Kind regards,

Technical Support / Project: PAW Rosetta+Flarmbat+3D Printed Box

« on: September 25, 2020, 09:54:44 am »

Hi all,

Forums live from people receiving and equally sharing. So after receiving lots of information from you (especially Ashley,Keith and Peter/ExfirePro) its time for me to share the result of my little project:

Goal: Build a EC carry on device for a SEP (Cessna 172), that can receive/send and that is compatible with Skydemon. + Flarm Direct was a requirement.

Timeline: Idea born to completion 3 months. 

Parts:
- PAW Rosetta
- Flarmbat (Powerflarm), 10h internal battery
- 2xJetvision Flarm Booster (to increase the Flarm reception)
- Powerbank Anker 10.000 Redux
- Cables: Juicybitz USB to MicroUSB + FTDI USB-RS232-WE-1800-BT 0.0
- Flarm+PAW are SUPERFANT Antennas.
- Self Printed 3D Case


Solution:
The Flarmbat sends FLARM and GPS to Rosetta via RS232 Cable.
The PAW Rosetta picks ups ADSB/ModeS/P3I and relays also the Flarmbat results to Skydemon
The Powerbank powers the PAW Rosetta. The Flarmbooster needs 60mA @ 5V-18V and is powered by one PAW USB output. The Flarmbat has 10h of internal battery life.
The Flarm Antenna is on a 1m cable and placed at the top of the windshield, the second Flarm antenna is on a 3m cable and placed with a suction cup in the middle of the read window.
The PAW Antenna was replaced by a SUPERFANT Antenna to reduce obscurance and is directly mounted to the device via SMA.
All works flawless, stable Flarm range with internal antennas in a metal body A/C is allround 15km. PAW Range to be analysed, but looking good


Important to me, that everything is in a contained box, therefore I printed a 3D case. Pictures attached.
I will upload pictures of installed unit in the A/C soon.

If further infos/pictures are out of interest, just reply and will try my best to provide asap.

So bottom line: Thanks to ExfirePro, Ashley, Keith and especially my dad, who put in lots of hours and clever ideas a successful project!

Kind Regards,
Patrick

OGN-R PilotAware / Re: New Stations Added

« on: September 18, 2020, 04:53:33 pm »

Hi again,

New station in Germany, Meppen1 up and running. It was built from scratch, there was no Flarm station before.
Currently it is without the Flarm antenna, which is still on order. Mlat range looks to be good with 50km at 2000ft.

Update: All three antennas are now up and at their final position. It was quite difficult to get those antennas up there, since there were not allowed to be attached to the roof or visible from the front of the house. https://ibb.co/1RT2FBX.

Kind regards,
Patrick

OGN-R PilotAware / Re: How to change position and name of OGN-R

« on: September 03, 2020, 09:30:29 pm »

Okay thanks Peter. That's pretty easy indeed.

One more question:

I bought a watertight box to put everything in, however space ways I can only use the right hand side USB slots (with the ethernet being on the left). I guess these are ports 3 and 4. Can I configure those to usb port for the Flarm and ADSB RTL sdr? E.g. the Flarm top right, ADSB bottom right. If yes, how do I do that?

Kind regards,
Patrick

What exactly does the coverage of a PW station say on gliderradar.com?

Is that coverage based on seen traffic with PAW equipped devices?

I am puzzles, because the coverage of the Flarm part of the station is so much different/more than the coverage of the PW part of the station.

Hi all,

new station up and running in Germany: EDDG / PWEDDG.
It was an OGN/Flarm station and is now upgraded to PW, using the existing Flarm antenna und cable.
View to south is great, to the north it is obstructed by some trees and hills.

A big thank you to Ashley and Keith for the great support!
More stations to come.

OGN-R PilotAware / How to change position and name of OGN-R

« on: August 31, 2020, 06:21:25 pm »

Hi there,

if I decide to move the location of an atom grid (e.g. because the location is not that good for coverage) how do I do that in an easy way?

Lat and long, height of antenna and station name would need to be changed.

Kind regards,

Patrick

Okay, understood. My objective apart from direct air2air coverage is also air2ground coverage for mode S/3D. I suspect line of sight is needed between P3I antenna and ground station with no metal obscurance.
So vertically and as high as possible in a top hand corner could be a good spot for a C172. In a GFK airframe I guess position is not so critical.

Kind regards,
Patrick

Ok so the yt set-up describes one P3I and one ADSB antenna, each in on top corner of the windshield.

Is for example the top right (or top left) hand corner a preferred position for the P3I antenna?

Kind regards,
Patrick

And if I may use the thread for antenna position.

In the PAW Mode S 3D YT Video it shows a C152 with optimised PAW antennas. https://youtu.be/J1imxhjG8ds, minute 12:37. 
It states that two PAW/P3i antennas are used, each located at the top corners of the wind shield.

Two questions:

1. Is the optimum position for PAW antenna in e.g. a Cessna as high as possible, so the obstruction from the engine is the least? Or in other words, the target is to have as most coverage of the ground as possible for atom station reception? Are there limitations as how near the antennas are allowed to be near Metal?

2. How did the use 2 antennas of one outlet? Any splitters you can recommend?

Kind regards
Patrick

OGN-R PilotAware / Re: Map of PilotAware / 360Radar ground stations -

Thanks for clarification.

And reading the PAW manual section Mode S/3D it will also show in Skydemon?

OGN-R PilotAware / Re: Map of PilotAware / 360Radar ground stations -

« on: August 19, 2020, 09:14:28 pm »

Yes we have, sorry for any confusion.

I was monitoring 360 radar today in the NW of Germany (around the city of Lingen) and was quite amazed by the result. It mlated traffic down to 1800ft realiably. Has there been new feeders or other updates in those area in the recent past?

And just to confirm: if an aircraft is successfully mlated on the 360 radar screen does that mean that I will see this same target as a bearing target in my Rosetta equipped aircraft when in range of an OGN-R?

Kind regards,

Patrick

Technical Support / Re: Connect PAW with Powermouse

« on: August 09, 2020, 06:33:18 pm »

Can I do anything from my end here to help?

Can I omit the data or phase in data from you, do some test flying and feed back the results?

Or will it be a fix via the update that is planned anyhow?

Thks for the investigation, I completely understand that if Flarm changes things that can have a negative effect on how Flarm and paw work.
A fix is much appreciated as of course the system should work as a whole.

Question: is there any problem in using the PAW radar while connected with the Flarmbat? So far my main problem is the SD visibility of traffic.
