Re: [Paparazzi-devel] GPS RTK

[Prof. Dr.-Ing. Heinrich Warmers]

Hi,
the UAV is the rover. On the ground station you have to implement  RTK. You  can do this with the navilog 407TTL or the ublox sam or t modules. This modules can send pseudo ranges.  You have to write messages  from the ground station to the GPS in the UAV.   The result is that the error in the rover is in the 30cm range.
To get a fix for the ground station you need up to 20 minutes.

I was think to to use this GPS in the UAV with paparazzi. some one can sometime on spend this ? GPS connetion has no problem, just need to see how to integrate data link of the Autopilot instead of the GPS data link.,with GCS as a RTK base station.
