Minimum Altitude

[Remo_Kilchmann]

Hello

I want to use a dji phantom v4 with litchi fly to make light measurements in stadiums. The problem is that some measurement points are at a height of 1m or 0.8m. Every time i add a waypoint with one of these heights, the drone hovers at about 2m or so. it happens in normal and above ground mode.

Does anyone have experience or the knowledge to fix this problem and fly the different points more accurately?

THANKS

One meter is within the vertical error range of height determined by barometric pressure. I would be very careful when flying with such close tolerances.

I don’t have a Phantom 4. I know it has sensors for horizontal positioning. I don’t know if it also uses them for landing protection which may cause the problem you are describing. You may want to see if you can temporarily disable the bottom sensors.
