Hello, I am currently conducting experiments with small VTOL aircraft for non-GPS flights using version 4.5.1 of Arduplane. With Arducopter I have successfully set the EKF origin and it is displaying the map marker correctly. However, I am encountering an issue with Arduplane where the map marker does not appear after setting the EKF origin, despite receiving a message confirming the successful setting of the EKF origin. I have tried using Mission Planner and the MAVProxy command line with the same result. I am unsure if this is a limitation of Arduplane or if I have misconfigured certain parameters.
My second question pertains to MAV_CMD_EXTERNAL_POSITION_ESTIMATE, support of which I understand was added in version 4.5.1. Can someone provide information on the correct usage of this command, particularly in relation to planes? Dead reckoning is a unique state for copters, but I am curious about when it triggers for planes. Any guidance on this matter would be greatly appreciated.
