drone link height issue
hi every one,
when using dronelink, i set my height to 45 meters, i use the reference "take of location", and not follow the terrain,
but when flying the dji air2s changes heright from 41 meters to 55. which when i put my drone pics into virtual survey the levels are all wrong,.
any helps with this issue. as i need to check lots of levels through out the site and with this issue i can not do my work
thank you
Ben

The drone has a barometric altimeter, which can have +/- 4m accuracy. This is a hardware limitation, which can be alleviated if you use a drone with RTK.
Are you saying the DL app is varying between 41m to 55m (134’ to 180’) which is about a 46’ altitude difference during the flight. Or do you mean the actual attitude between the drone and the ground is varying between those altitudes ? I’ve never had anything more than about a couple feet difference displayed in the App than what my mission altitude was set to while running any ATL missions. Even with the inaccuracy of these drones if it’s varying that much it sounds like it may be a drone issue. Maybe if you share the plan someone can take a look at it and possibly see why. Seems like there is something else other than the app. Can’t hurt to take a look.
I ran a small mapping component yesterday set at 100’ altitude using ATL as reference. The DL app indicated 99’ to 101’ during the mission. So there were no issues as it ran within 1’ of the set altitude. I’d go through the drone and calibrate and/ or refresh the firmware if it’s actually flying the mission with the altitude varying 30’ off or more. My testing revealed it’s working correctly.
