m500 local positioning problems
-
Hi,
The gps module on the surface appears to be working okay (drone has GPS lock, gps is reporting data to correct mavros topics etc). However, when I actually observe that data, some component of the drone is feeding in absolute garbage. /mavros/local_position/pose, which to my understanding references the GPS and a few other components on the drone to form a composite local position, has major drift in the x and y directions (while sitting completely still on the ground, the topic will register the drone moving at about half a meter per second) and the z direction reads in as the drone being 800 meters below 0.
I have performed all of the calibrations I could find on QGC, like the compass and the accelerometer, and before that reset the drone to factory settings and configured everything with the command it prompts you to run upon reflashing the board.
Do you have any ideas what the problem might be? I have tried swapping out multiple GPS modules and this problem is consistent across several m500s we have right now.
