Guidance Motion high drift

[AlexisTM]

Hi,

The motion (position) output of the guidance system (after calibration & setting the position of the sensors) is heavily drifting. What should I do to reduce the drift ? Why does it drift that much ?

Did You use Guidance along with a DJI flight controller?
Also, the precision is heavily influenced by the environment. Good lighting, rich texture and regular motion should give You reasonably good result.

Dear,
It was with ROS, but we have an A3, not a M100. Therefore, it is no DJI Flight Controller connected to it.

Guidance has a poor onboard IMU. Try to connect Guidance with a DJI flight controller. A3 should also work.

Thanks, I will try 2016-12-02 14:26 GMT+01:00 tangketan <notifications@github.com>:

Will there be any chance to be able to send the quaternion to the Guidance System from a ROS node?

Hi @AlexisTM, were you able to solve the high drift problem, i am also facing this problem and can't seem to be able to fix it.

Also did you figure anything out about being able to send quaternion to the guidance from ROS?

[AlexisTM]

No, it did not work. We switched to the PX4Flow for vision odometry and stereo camera for obstacle avoidance. Le mer. 29 mars 2017 05:26, dan748 <notifications@github.com> a écrit :
