Re: [Paparazzi-devel] AR Drone 2.0 Getting Flight Location Data

[Pascal Fust]

Hi Nathan,

If you go with the log data, you need to ensure that the clocks of the sensor and the GPS of the log are synchronous, or the time lag between the two at least known...

Cheers,

Pascal

The flight history data is stored under var/logs/<date and time>.data.
These can be replayed via the GCS.

Messages received from the drone should be on the ivybus. You can
write a program that will read GPS messages as they come in.

Heres a python example for sending a message
