I think there is a bug here:
When you configure DJI D-RTK (ground segment) it asks for "elipsoidal height" (without saying what datum and coordinate system)
I used a Trimble R8 GNSS GPS with the following measurements for the DJI D-RTK Base:
Lat: 42.16877139 N
Long: -8.68799987 W
Height: 523.294 m (elipsoidal WGS84)
With this good coordinates from Trimble GPS, the RTK is blinking all the time: red and green (not fixed).
But If I get the same point coordinates from Google Earth (not very good coordinates) like this:
Heigh: 456 m
Then D-RTK works, the LED is "FIXED GREEN" (it Works).
But as you can see there is a big difference: 523.294 - 456 = 67.294 m
My questions are three:
(1) Is not very dangerous to Land or use waypoint with Google Earth coordinates in the D-RTK base since there is 67 m of difference?
(2) What datum and system is asking DJI Assistant 2?
(3) Why the DJI GPS (D-RTK ) is not accepting real and true GPS coordinates (WGS84) from a good Trimble GPS,
but it is accepting not very good Google Earth coordinates?
