Check your vibration levels and yout notch filter settings.

Was there a GPS glitch?

I initially suspected the GPS was the problem, so I replaced it with a CUAV GPS, but the result was the same.

**The vibration, I also checked the log, it’s fine.

I found that this problem only occurs when making sharp turns, so I’ll try reducing the turning angle first.**

The altitude difference is large, it could be a problem with the barometer.
