Inertial based Integration with Transformed INS Mechanization in Earth Frame
Lubin Chang, Jingbo Di, Fangjun Qin
This paper proposes to use a newly-derived transformed inertial navigation system (INS) mechanization to fuse INS with other complementary navigation systems. Through formulating t…
Strapdown Inertial Navigation System Initial Alignment based on Group of Double Direct Spatial Isometries
Lubin Chang, Fangjun Qin, Jiangning Xu
The task of strapdown inertial navigation system (SINS) initial alignment is to calculate the attitude transformation matrix from body frame to navigation frame. In this paper, suc…
SE(3) based Extended Kalman Filter for Spacecraft Attitude Estimation
Lubin Chang
In this paper, the spacecraft attitude estimation problem has been investigated making use of the concept of matrix Lie group. Through formulation of the attitude and gyroscope bia…
Semi-Analytic Method for SINS Attitude and Parameters Online Estimation
Lubin Chang
In this note, the attitude and inertial sensors drift biases estimation for Strapdown inertial navigation system is investigated. A semi-analytic method is proposed, which contains…
Alternate Derivation of Geometric Extended Kalman Filter by MEKF Approach
Lubin Chang
This note is devoted to deriving the measurement update of the geometric extended Kalman filter using the multiplicative extended Kalman filtering approach, resulting in the attitu…
Dynamic Analytical Initialization Method for Spacecraft Attitude Estimators
Lubin Chang, Fangjun Qin
This paper proposes a dynamic analytical initialization method for spacecraft attitude estimators. In the proposed method, the desired attitude matrix is decomposed into two parts:…
