Robust Attitude Estimation Using IMU-Only Measurements

WebJul 25, 2024 · Ii-C Extended Kalman filter for attitude estimation. The EKF is widely used in attitude estimation to fuse the measurements from gyroscopes, accelerometers, and magnetometers for a single, accurate estimate of the orientation. The orientation is estimated recursively by performing a prediction update and a correction update. WebMost satellites use an on-board attitude estimation system, based on available sensors. In the case of low-cost satellites, which are of increasing interest, it is usual to use magnetometers and Sun sensors. A Kalman filter is commonly recommended for the estimation, to simultaneously exploit the information from sensors and from a … twitter juniorjfive
