Furthermore, two methods were introduced to ensure alignment accuracy and speed: (1) shortened rotating cycle and redesigned compass parameters were selected to eliminate or ease the amplification to low-frequency senor error A method using neural network (NN) and wavelet-based de-noising technology is introduced into the SINS/GPS/magnetometer integrated navigation system, because system accuracy may decrease during GPS outages. This method is accomplished by utilizing the different error propagation characteristics of two different level alignment algorithms, and the procedure of azimuth alignment is performed by opening the azimuth loop.

The simulation results show that the precision of the azimuth misalignment angle in the platform inertial coordinate is not preferable, however, the misalignment angle in the geocentric inertial coordinate achieves an v. On the other hand, azimuth alignment errors converge much more gradually. LiuJ.

Error time histories are presented for a number of cases to show the interrelationship of important factors such as latitude, inertial sensor errors, measurement noises, and disturbance characteristics.Article · Jun 2000 ChenX.-Q.

For most navigation systems, the initial azimuth is often large by suffering from much external interference, the linear error model based on small misalignment angle is unsuitable to express the error

For the error of the rotation unit, a finite memory Kalman filter is applied to estimate the states during the initial alignment. Based on a certain SINS, turntable test proves that alignment accuracy and time were significantly improved and slightly shortened in comparison with the classical compass alignment.

When the GPS is working well, NN is trained using the velocity and position information provided by SINS as input and the corresponding errors as output. On the basis of the local obsersability analysis, a robust adaptive filter is developed to estimate the attitude angle error for SINS rapid transfer alignment. the principle of the platform inertial navigation system which tracks the inertial coordinate is introduced firstly, then the transfer alignment methods in two kinds of inertial coordinate (the platform inertial coordinate Furthermore, based on analysis of velocity error, latitude error, and acceleration error on moving base, two improvements are introduced to ensure alignment accuracy and speed: (1) the system parameters are redesigned
