Performance Analysis of Three Attitude Algorithms for SINS

Abstract

The attitude algorithms can enormously affect the navigation accuracy of SINS and Runge-kutta algorithm, Peano-Baker approximation algorithm and rotation vector algorithm are the common algorithms in engineering application. Analysis and comparison are done to the above three algorithms in this paper, the three algorithms are simulated and verified under coning motion and the result show that under the condition of low angle vibration , fourth-order Runge-kutta algorithm has the best comprehensiveperformance.
