Hello everyone,
I am trying to understand the different altitude-measurements/calculations from the flight record, does anybody know the differences? I found 5 columns which have something to do with height:
IMU_ATTI(0):press: D
IMU_ATTI(0):alti: D
IMUCalcs(0):height:C
GPS:heightMSL
osd_data:relativeHeight
When I plot them there are visibible differences (look attachment if this is too small).
What I know:
IMU_ATTI(0):press: D → the height derived from barometric pressure
GPS:heightMSL → the height above mean sea level.
I'm not sure how the other altitudes are being calculated and how exact they are, respectively. if anybody knows, please let me know!
Greetings
