I want to do experiments with advanced telemetry over IP. I already have a paparazzi3-patch that adds a new target "linux" building paparazzi as a usermode-program for a Linux-based airborne computer.
Now I want to implement the uart-emulation for it to communication to the ground-station.
On the 24c3 I saw telemetry being passed via TCP/IP ove the internet. Where can I find the protocoll-specification
and the ground-station -code for it, so I can use the existing ground-station-code and just implement the airborne-code to directly speak this protocoll?
I'll am also writing another emulated uart to create a
tcp-connection to gpsd and act like it is a directly attached gps-receiver while in fact it is the gpsd that also serves gps-data to the payload and creates a local nmea or gpx -log inside the aircraft and keeps the local clock correct.
