Hi Rui,

That site you linked claimed their transmitters include up to 48kbps RS232 on a sidechannel for exactly these purposes. If that's true, it should be plug and play as long as you use the transparent serial protocol and a level adapter if necessary.

Cheers,

Hi all,


I would like to have a range of 50Km for my UAV.

For it I can use:

- For RC control the Long Range EZUHF 433MHz system (someone archieved 80Km+
range);
- For video transmission the PST1 PCB Video Transmitter [2.4GHz - 2 W] from:
http://www.advmw.com/uav_transmitter_pst1.html
- And the data-link for the paparazzi communication I'm using the Aerocomm
868MHz but is limited to 250mW and have a duty Cycle of 10%.


I have an ideia to improve the range of the telemetry data-link for
paparazzi. Maybe I can use the PST1 Video TX to send also in the data
carrier the telemetry data from paparazzi autopilot. And use another modem
system to carrier the link from the GCS to airborne. Maybe I can use the
XBee Pro 868MHz just to send the commands from the GCS to the airborne
autopilot.

What you think? It's a good solution? Will work? It's easy to implement?

Please, give some sugestions about this issue. It would be nice to archieve
a mission UAV with a range of 50Km.



Best regards
Rui Costa
