WebJul 26, 2024 · In contrast, the rough IMU preintegration and INS mechanization without compensating for the Earth rotation yields notable accuracy degradation. When the GNSS-outage time is 60 seconds, the degradation can be 200% for the industrial-grade MEMS module and more than 10% for the consumer-grade MEMS chip. WebFor each IMU body frame, IMU will give you 3 by 1 vector which is the rotation velocity.
