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.

In Inner-Formation gravity field measurement satellite System (IFS), the inner satellite travels in a pure gravitational orbit within the cavity of outer satellite. Compelled by spatial non-gravitational forces and internal interferences, the outer satellite generates relative position and attitude drifts.

The Influence of Gravity Disturbance on High-Precision Long-Time INS and Its Compensation Method
2014 Fourth International Conference on Instrumentation and Measurement, Computer, Communication and Control, 2014The influence of gravity disturbance vector can't be neglected in high-precision long-time inertial navigation system (INS). In this paper, proceeding from INS arrange equations, we establish an error model of INS with gravity disturbance vector, and discuss on the basis of a case study of single channel how gravity disturbance vector influences INS in

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

The trajectory tracking control of a quadrotor unmanned aerial vehicle is done in this paper in the presence of changes in the center of gravity due to the variations of a connected load mass and its position, external disturbances, and parametric uncertainties. At first, dynamic equations are obtained using Newton–Euler relations, and then a two-loop
