I have been recently testing Here+ RTK(firmware version 1.30) with Pixhawk2(Standard Cube version). After the observation with 1m accuracy, I found that the X and Y coordinates of the base station were very precise. But I’m more concerned about the Z value, which is showing approximately 90m error compared to the actual value.
Actual Z value = 866m
Here+ Base station reading after observation (z value) = 777.598m
The survey was conducted in open space with no trees or any obstacles around and there was a minimum of 20 satellites connected during this observation.
Kindly help me how to overcome this problem.
Thanks in advance.
