Novel Special Orthogonal Group Optimization for Coarse Alignment Method of SINS on a Rocking Base
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 In order to solve the coarse alignment problem of the strapdown inertial navigation system on a rocking base, a fast coarse alignment method using the Special Orthogonal Group optimization has been proposed in this paper. In this method, based on the alignment idea of tracing gravitational apparent motion in inertial frame, the model of coarse ...

Robust adaptive Kalman filter for strapdown inertial navigation system dynamic alignment
IET Radar, Sonar &Navigation, Volume 15, Issue 12, Page 1583-1593, December 2021., 2021 Abstract The measurement noise covariance R plays a vital role in the Kalman filter (KF) algorithm. Traditionally, a constant R is obtained by experience or experiments. However, the KF cannot achieve optimal estimation using constant R under non‐Gaussian conditions.

IET Radar, Sonar &Navigation, Volume 15, Issue 12, Page 1727-1735, December 2021., 2021 Abstract The issue of non‐linear robust state estimation in the integration of a strapdown inertial navigation system and global positioning system is addressed in this study. Based on the cubature Kalman filtering frame, a non‐linear robust filter called a robust cubature Kalman filter (RCKF) was introduced to address the outliers and the inaccurate ...
