Hi, I am new to flying the M300RTK and came across a few anomilies I was unable to resolve...if anyone has any insight I would be most grateful.
Using only the DJI Pilot app on the smart controller and the D-RTK base station I was only "allowed" to set a flight altitude of 40ft as the minimum, using the Zenmuse P1 sensor this gives roughly a 0.15cm GSD for an ortho mission. A project I am working on is wanting to fly at only 25ft to attain 0.10cm GSD. Is there a reason I cannot change this value below 40ft? The same question exists in terrain follow mode as it seems restricted to 82.1ft, is there a reason for this or something I am missing to change this value?
On the terrain follow mode I have another question, after uploading a Digital Surface Model and loading it into the mission plan all seemed to make sense, the aircraft was going to fly 82.1ft above the DSM derived data, the mission altitude display showed that it would fly DSM+82.1ft, however, on launching the mission the M300 flew 130ft higher than was anticipated, but followed the terrain as expected, so at DSM+212.1ft.
I have been reading about ellipsoidal height vs gps derived but 130ft seems excessive in my mind but it is not a strong subject for me yet.
Any suggestions??
Many thanks.
