Hi, I am currently doing a project of drone to loiter in an indoor environment where GPS is unavailable. In this case, I use POZYX to do my indoor positioning and followed the steps on ardupilot website (http://ardupilot.org/copter/docs/common-pozyx.html ). However, my ground station (Mission Planner) does not show the location of my drone on its Flight Plan. Anyone has suggestion to solve this? Or is there any additional parameter settings that need to be done? Any help is much appreciated. Thank you.
