OGN-R PilotAware / Re: OGN PAW up link do not see PAW trafic ( resolved )

« on: September 09, 2017, 01:46:52 pm »

For what it's worth, I'm running pretty much the same setup as Andrzej, and it does work OK for me. My version does not run 0.2.6 though, it's 0.2.5?

Hi Lee,
I only had the radar screen active. There was a big yellow button in the top rh corner of the radar, labelled "GS-OGN 1", I guess that was due to my OGN node being active? Not sure if that station right on top plays a role.

That is correct. I had the radar screen open all the time and I was curious to see how it interacted with the OGN-R node.

My stats on the PAW clearly show they see eachother well:

Added the first OGN-R Ground station in the center of The Netherlands, callsign PWHlaken!

If any of you fly nearby, let me know if you see traffic through the OGN network.

Hi gents,

This is to report that my OGN-R node PWHlaken is up and running in the center of The Netherlands. Due to weather constraints the antenna is still a temporary setup, but all seems to work as expected. Hope to see some traffic activity soon!

Yeaterday I received my bridgeboard and built the PilotAware system using the latest image. All seemed to work OK, except it suddenly lost GPS connectivity. The system log shows what appears to be a resource conflict. Unplugging and re-inserting the USB GPS resolves the issue (for now).

OGN-R PilotAware / Re: New Stations Added

« on: July 28, 2017, 08:37:32 pm »

Hi Lee,

I meant if there were any licenses or restrictions to operate a base station on the 'license free' 869MHz band. I have just found official statements that in The Netherlands there's no problem as long as you stay below a certain ERP power (looks like 500mW), and below a certain duty cycle as to not hog the band.

I'm interested in setting up a station in The Netherlands, so I just sent an email to ogn@pilotaware.com as well.

Would OGN-PAW stations outside the UK be useful at all? And would it be legal?
What limitations exist for base stations with 869MHz transmitters in various countries? Do they need a license?

I've flown an aircraft fitted with PowerFLARM, and it has picked up FLARM equipped gliders at greater than 10km.

For collision avoidance at normal light GA speeds, my thinking is that initial contact at 5km would be more than enough.

Agree. Two GA aircraft cruising head-on at 100 kts would bridge a 5km gap in 50 seconds. Seems reasonable that you'd have plenty of time to look outside and apply see-and-avoid. Not sure about UK, but in The Netherlands, Flight information service warns for other traffic ~2 miles ahead and that seems fine.

I don't understand the urge to see traffic 50 miles away. Nice for ground stations monitoring, but of no use to a GA pilot looking for an extra pair of 'eyes'.

General Discussion / Re: Paw and AVMAP EKP V

« on: April 03, 2016, 07:45:52 pm »

The XRX supports a few 'profiles' for external EFIS systems. In my docs, profile 1 is for AnywhereMap, profile 2 for Trueflight. Garmin support only exists in V2.0 firmware, which is the last one released before Zaon went belly-up.

I will ask Avmap which Zaon protocol/profile they support, as they claim compatibility but their manual shows no info which profile should be selected. My demo uses the binary format described in a hard-copy Tech Reference manual from 2006 and not available online. This manual claims this binary format is 'Trueflight' mode.

Edit: The EKP-V manual *does* show which profile to use, they list profile 1. Their previous product EKP-IV shows profile 2. So they have switched, I guess?

Edit again: Avmap probably should take the opportunity to natively support $PFLAA/PFLAU traffic inputs. They have an external GPS antenna that is just a uBlox, so if they instead allow PAW to be the GPS and traffic source, they are all done.

Hi Lee,

The connection is RS-232 at 57600 Baud. The protocol is a binary data blob with values and bit fields. The protocol requires both sending and receiving data, as some of the Zaon settings coming from the device (PocketFMS, EKP-V) are echo'ed back in the binary blob for verification.

I will contact you offline about the manual, not sure if I can send a copy due to copyrights.

Hi Federico,

I am working on something like this in a stand-alone translation gadget. I am at 50%, my code generates valid Zaon XRX data. Quick demo with PocketFMS:
https://youtu.be/82Hj2XWtQg8

Unfortunately I have a bit of difficulty with my EKP-V right now or I would be able to test this too.
Next step is translating $PFLAA and $PFLAU messages from PAW and selecting the most imminent threats to display. The Zaon protocol only supports three simultaneous threats to display.

NATS do not currently provide the 1090 ES date to ATC although they have a system on trial across the south of England which currently is receiving and recording ES data for analysis and has been used to validate and analyse those transponders that have been used to broadcast non certified GPS position date.

It's funny to see how technology moves so much faster than reality in the established organisations. I work in IT, and when the traditional IT departments can't or won't deliver certain functionality, users work around it and start using Dropbox, Onedrive etc. We call this 'shadow IT'.

Same is happening in aviation now. Here in The Netherlands, Dutch Mil is so understaffed that they don't even deliver basic service anymore (as stated in NOTAMs). They also do not provide access to their data streams from 1090 ES. So when I arrived at EHTX (Texel) yesterday, the tower guys have a nice big screen with FlightRadar24 on it. Real-time ADSB 1090 ES tracking, not bound to any official organisation, but entirely usable. This is 'aviation shadow IT'. And so is PAW. PAW is 'give me TCAS, but not at the cost and rigidity of real TCAS'.

Do note that those cheap PL2303 ones are actually fake chips copied in China, not from Prolific. They work OK, but Prolific is doing everything they can to make them fail in their Windows drivers. Built-in Windows WHQL drivers from Windows 8(.1?) and up refuse to start when they detect a fake chip.

You can still find older drivers online that work with these fake chips, but chances are you get more software than you bargained for. I have had a number of downloads flagged as infected with virus and trojans. So be careful out there.

For PAW and Linux it is less of a problem as these chips work fine with the generic Linux kernel drivers.
