As for the altitude accuracy, make sure you are looking at the VPS readout, not the GPS readout. When you hover close to the ground, the bottom sensors come into play and the VPS readout is usually spot on. GPS however is +/- about 3' if I remember correctly. So use VPS for low altitude and GPS for higher altitudes.
Hi Paul,
GPS readout? GPS is not used for Altitude in any way on DJI drones.
Height is measured by a baromeric sensor, at takeoff the height iss re-set to zero, as a reference height for the flight.
At low altitude and in VPS range the height is also measured by the bottom sensor, but not seen on a MM as MM shows only the barometric height.
cheers
