Drone position changes after RTK differential data loss

During my drone testing, I noticed that after taking off and hovering from the RTK fixed state (fix_type=6), the fix_type changes to 4 or 3 when I disconnected the RTK ground station. As a result, the drone’s position also changed. Is there any way to prevent the position from changing during this transition?

How much did it change for your case? Do you have a logfile? If so, it would be nice if you could upload it to logs.px4.io for us to check.

Thank you very much for your reply. Move approximately 2 meters horizontally. Is this change normal when the GPS status changes from 6 to 3?

My gut feeling is that this is somewhat expected. Not sure I have a better answer than that.
