Im sorry but is note the case….
While just activation voxl vision px4 service from fredh resceived voxl cam, voxl output local frame pos and velocitys via mavlink.
so how to activate local to body frame velocity transformation?
Maybe with px4 this work but with ardupilot i check on mavlink analys and i make simple translations and i can ensure you that voxl send out local frame pos and vels.
Maybe you can tell me ou to force voxl to output local frame pos but body frame vels to ardupilot ?
Thank you so much.
