Re: [Paparazzi-devel] UAV position in paparazzi GCS

[Henri Pierre]

Hi

@Felix
Yes, my Home waypoint is at 0,0.
In my example, I moved home waypoint, but any waypoint moved to the coordinates of the
uav does not surimposed the uav. On the map, waypoint seems to be at the right position while 
uav seems not.

I will upgrade to latest 3.9 and try.

@Bernie, 
Thanks for your help but as explained above moving a waypoint seems to be correctly represented on 
the map.

Regards
Henri

Even if the maps have an offset the HOME waypoint should still be at exactly the same location as the uav in the sim.

I also tested it with this location (default simulator location set in conf/jsbsim/aircrafts/reset00.xml)

Dont discount the thought that google maps/earth could be wrong for this area.
At my home google earth/maps is very close but at my parents farm the images are way out of position 40-80 meters. Images of a creek are positioned on the side of a hill!

Cheers,
Bernie.
