RTH not accurate

[terry615]

I have noticed after the recent firmware update that RTH/Percision landing is off about 20-25 feet. Before the update it was very accurate has anyone noticed a difference? DJI support suggested to recalibrate the IMU any help would be greatly appreciated

Are you flying straight up 20 to 30 feet upon takeoff? If so and your RTH is still off by 20 to 25 feet then there is definitely a problem.

Yes I go to 25 feet and hover 10-20 seconds before I start to fly

That 25ft sounds suspiciously like what would happen if you set the RTH landing point to be at the RC instead of the take off point.

Did you double check your RTH settings?

I thought the same thing and I have checked that. Also I read somewhere every time it powers up it defaults to gps home point location. I will double check that setting again just to make sure

So just updating this thread, After uploading my flight logs I see my GPS started having issues after I upgraded to .900 firmware. Going to downgrade to .800 to see if that helps. Attached are before and after GPS reception.
