Question
Technology

Which outcome occurs when a MEMS gyroscope in a quadcopter experiences prolonged, high frequency mechanical vibration?

A)Drift increases position estimate errors.
B)Motor speed governors start oscillating.
C)Battery lifespan significantly extends.
D)GPS signal accuracy becomes superior.

💡 Explanation

Increased vibration accelerates the **Allan variance** of the gyroscope signal resulting in integrating small errors over time impacting positional accuracy causing drift. Therefore, larger positional estimation errors occur, rather than improved GPS or battery performance, because of inaccurate inertial measurements.
