On gravity disturbance compensation technology of high-precision SINS based on B-spline method
Proceedings of 2014 IEEE Chinese Guidance, Navigation and Control Conference, 2014Errors of high-precision strapdown inertial navigation system (SINS) resulted by gravity disturbance vector cannot be neglected. After analyzed principal of how gravity disturbance affects precision of SINS, the errors induced by gravity disturbance were compensated using B-spline least-square method.

Abstract With the increasing demands for long-endurance and high-accuracy inertial navigation system (INS), gravity disturbance has been identified as one of the major error sources with decisive effects on the performance of INS. To address the problem, this paper proposes an autonomous and high-accuracy gravity disturbance compensation

Mechanical Stabilization in Robotic Bionic Eyes with Gravity and Disturbance Compensations
2019 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2019The vibration of the robot during the movement brings various irregular motion disturbances to the robot’s head, these vibration results into unstable images captures by the head-mounted vision system and therefor the vision system cannot accurately perceive the environment.

An improved method for gravity disturbances compensation in INS/GPS integrated navigation
2014 12th International Conference on Signal Processing (ICSP), 2014Though the gravity-induced velocity and position errors can be easily dumped in GPS/INS integrated navigation, the attitude estimation errors are more affected by the gravity disturbance errors. In this paper, an improved gravity disturbance compensation method is performed to reduce the gravity-induced attitude measurement error in inertial navigation
