I am familiar with GPS and barometric variations and when I began using Waypoints I was not at all shocked or surprised by what I experienced. I never even gave it a second thought but I can understand how many people would expect greater accuracy. The barometer changes regularly so we can or should understand that changes to that would affect the accuracy from day to day and even from hour to hour. With regard to GPS altitude the triangulation of an object on the surface can be pretty accurate but GPS satellites can't provide the same accuracy with regard to the height of an object. The position of the satellite group from day to day and over several hours will cause significant variations in the GPS reading for the height of any object. This is not a fault of DJI, it's a matter of triangulation. We should be able to expect a decent accuracy with regard to the horizontal position of our drones but the vertical accuracy will always be a crap shoot and that reflects my experience.
I'm experiencing the exact same issues with my Mavic 3 Classic.
According to the specs, the drone should be accurate to within 3 feet vertically and 10 feet horizontally.
It's not even CLOSE to that! Despite calibrating and taking of at the exact same location, every time.
I took a job filming the progress of a construction and am struggling to bring myself to charge for the resulting video.
Worse than the huge drifts of the drone itself, is that it can’t event orient itself towards the POI consistently, making it close to impossible to join the footage, even with excessive cropping. Sometimes the POI is centered in the frame, sometimes waaay to the left or right – even if I fly the waypoint mission several times back to back on the same day, it’s positioning and orientation shifts each time.
When confronting DJI with the appalling gap between the specs and the actual performance, the supporter – after conferring with the “engineers”, said it was because the waypoints – get this – WASN’T DRAWN IN A PERFECT CIRCLE AROUND THE POI!!!
