Hello,

I am getting “PreArm: 3D Accel calibration needed” while using SITL in mission planner. I tried changing the accelerometer parameters but did not help. Any suggestions?

Thanks

Reset the parameters to default. The parameters are populated with values that work.

you need to add plane.parm (1.7 KB) in sitl\default_params.

we need small INS_ACC offsets so INS is recognised as being calibrated

INS_ACCOFFS_X 0.001
INS_ACCOFFS_Y 0.001
INS_ACCOFFS_Z 0.001
