OGN tracker with Stratux Europe

[kaelsaes]

Hi,

thanks for your great project.

I'm using your OGN tracker together with my Stratux Europe traffic awareness device.

I love the additional option to send P3I (PilotAware) signals.

My PilotAware Rosetta receives the P3I signals from Stratux Europe / OGN tracker.
But the signals are sent to rare. Sometimes Rosetta has to wait 60 seconds or more to receive a P3I signal even though both devices are placed next to each other.

Do I have an issue with my OGN tracker or is this normal operation?

Thanks in advance.

Best regards
Kai

It is most likely that the device is not moving.
When moving more than 1m/s the OGNTP packet should be sent at 1Hz rate and the PilotAware packet at about 1/4Hz.
When not moving the rates are about 4 times lower.
This is all still subject to optimization, basically the rules of 1% duty must be kept and the OGNTP packets being 5ms, P3I being 8ms long, then there is LoRaWAN which is transmitted at about 1/60Hz and packets are about 60ms long, and yet FANET packets, at about 1/20Hz rate 30ms long.
If you can, please check what happens when the OGN-Tracker is moving more than 1m/s.

I have tested last week in my car. The problem still appeared.
I will test in flight when the weather becomes better.
Is FANET already available?

Please send me the Stratux .ogn log files from your car test via the private channel.
I can then see how often the P3I position was transmitted.

I have sent the log files.

Thanks
