단일 안테나 GPS와 가속도계를 이용한 저급 IMU의 자세 보정
Attitude Compensation of Low-cost IMU Using Single Antenna GPS and Accelerometers
초록
In this paper, the error compensation method of the attitude reference system with low-cost IMU is proposed. In general, the attitude error calculated by gyro grows with time. Therefore the additional information is required to compensate the drift. The attitude angles can be bound by accelerometer mixing algorithm and the heading angle can be aided by GPS velocity information. The Kalman filter is used for error compensation. The result is verified by comparing with the attitude calculated by medium-grade IMU, LP-81.
