I was flying my spark yesterday. And it starting to show different heights. I was flying about 100m up when it started to show my that i am 5m above the grond. I can in to land and changed out the batteries. And then launched again and about 20m up the same thing with the height jumping. Can anyone please help!!!!!

It wasn’t misty by any chance? The vertical positioning system can sometimes get confused in misty conditions due to unwanted reflections of the underside infrared emitter.

Hi there. No it was mid day with no clouds. With a very light wind.

Hi, thank you for reaching out and we do apologize for the inconvenience. Can you please try to calibrate your IMU to see if the problem persists? Also, If can fly in a different location that would be great for us to check if you still experience the same issue. Please keep us posted. Thank you for your understanding and support!

Old story to tell.....no re calibration will help nor other location....The reason is the barometer inside the spark its toasted or you have a spark with a barometer from another manufacturer that cant work properly with the new firmware..... check my previous post https://forum.dji.com/forum.php?mod=viewthread&tid=159327 and dont listen admins or anyone else they will tell you to sent it for repair bla bla bla......
