Hello community. I am trying to use only imu, barometer, and magnetic compass for offboard control. I want the odometry information to from these sensors only. How to achieve that?
It seems that I have to use either gps, vision-inertial sensors, or optical flow to switch to the offboard mode. However, if I use these sensors, many times it outputs no reliable position estimates and refuse offboard switch. My application does not require precise localization.
Thank you very much for your reply. We also check the offboard documentation page. It says it needs position or pose/attitude information - e.g. GPS, optical flow, visual-inertial odometry, mocap, etc.

Does this mean if we only use IMU, barometer and magenetic compass, it will not be able to switch to offboard. Indeed, we will use thrust and altitude control and will not send “set position” command.
