Hi all ,
I want to know what is the source for altitude in mission planner HUD
Is it GPS / Baro / something else ?
when I set the EKF2 source alt to GPS / Baro Dose it change in the HUD ?
when I move mouse in the Map in Flight plane it show the alt of home location such as 500 m ASL
BUT when gps lock the alt-asl value is about 512 mASL 0m AGL why this error and how to solve it ?
many time after power the plane alt start at 0 then move up and down even the plane not moving and sat no. 9 to 11 and HDOP 0.9
What is more accurate GPS or Baro ?
Hope any one can help with solution for these Questions ?
best regards .
