After launching Flight Deck, the odometry section displays coordinates and altitude correctly.
After ARM, the altitude and coordinates start to change, although the drone stays in place. After a few seconds, the service stops.
What could be the reason?

Hi @Pavel-Ardashov ,

Can you please describe your setup?  Is the flight deck attached to a custom vehicle?  How is it mounted?

I watched the video and saw the data rising.  I couldn't tell, are the props actually moving?  Or is the vehicle totally static?

Hi @modaltb 
Flight deck attached to a custom drone.
After ARM, the propellers were spinning, but the drone remained in place, as you can see in the video. The video from the Hires camera is displayed on the monitor![изображение_viber_2021-10-21_08-34-00-588.jpg](https://forum.modalai.com/assets/uploads/files/1634794812463-изображение_viber_2021-10-21_08-34-00-588.jpg) .

Thank you, the issue was resolved on my own.
An additional box helped to close the barometer. After installing it, there is no problem with height data.

Hi @Pavel-Ardashov ,

Thank you for the information, did you FlightDeck not have a barometer cap included?  We should have shipped it with a little 3D printed cap.

@modaltb my FlightDeck have a barometer 3D printed cap.
But it was not tight, there was a groove in it. Maybe it was planned?
By completely closing the barometer, we fixed the problem.
