Hmm, lots of questions here
A) This is to provide GPS info into your mode S transponder so it can transmit position info. We have a funkwerk mode S transponder which I think may work with this so is interesting.
Can you tell me what you are referring to ?
I think you may be talking about the early work I did to get an RS232 stream of NMEA sentences out
of PilotAware ?
If so, I prototyped this a while back, and managed to feed a stream of NMEA sentences to the RS232 port on my PC
This could be connected to a Mode S Transponder if desired.
Some configuration setup needs to be done, some transponders use different baud rates.
B) It's not currently legal to connect this (this is what the NATS ADS-B trial is doing)
I hear that this ruling is to be relaxed very shortly
C) Without this, only other PilotAware devices will see position info for you.
Correct, as received on the P3I RF
Also, this is where the model B (rather than B+) stops working as a solution as 3 (or 4 with the GPS dongle) USB ports are required.
This does confuse me, I am using a Pi B+, this works fine, are you thinking that a Pi B+ does not work with PilotAware ?
The issue with PilotAware, is that it does not yet work with the Pi 2
Thx
