Initial alignment is of vital importance to inertial navigation systems (INS). The two main methods of self-alignment, the traditional gyro-compassing alignment method and the Kalman filter method, are discussed. We apply and compare the two methods via simulation and test in use of a strapdown inertial navigation system (SINS) based fiber optic gyroscope (FOG), respectively. The simulation and test...
Initial alignment is of vital importance to inertial navigation systems (INS). There are mailnly two popular methods in self-alignment, which are traditional gyrocompassing alignment algorithm and kalman filter algorithm. After giving the basic principle of the two, we do some simulation and test in use of INS based fiber opitic gyroscope (FOG). The simulation and real experiment show that kalman...
