Research on Algorithms for Multi‐Vector Attitude Determination

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
Various attitude estimation methods are based on an optimization problem posed in 1965 by Grace Wahba, which is called Wahba’s problem in the field of attitude estimation. As a key for attitude determination, many different algorithms for minimizing Wahba’s loss function have been proposed in the past 60 years.

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.

Singular value decomposition‐based iterative robust cubature Kalman filtering and its application for integrated global positioning system/strapdown inertial navigation system navigation

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 ...
