Why are gyroscope readings often integrated with accelerometers and magnetometers in navigation systems?
Answer
To correct for the drift error that accumulates over time
Gyroscopes provide excellent high-frequency rate-of-turn data, but their calculated orientation suffers from accumulated drift; accelerometers and magnetometers provide corrected, long-term references to mitigate this error through sensor fusion.
