摘要
提出了偏振光/GPS/SINS组合导航方法。推导了偏振光辅助测姿原理并进行了仿真验证。提出了多模块改善能观度的方法。采用联邦卡尔曼滤波方法实现了组合导航算法,利用Matlab仿真方式分别对使用单偏振光模块和多偏振光模块的组合导航系统的测姿修正效果和能观度改善效果进行了检验。结果表明偏振光辅助测姿方法的引入能够大大改善导航系统的能观度和精度,非平行观测的多偏振光模块可以进一步提高系统性能。
A new method of polarized-light（PL）/GPS/SINS integrated navigation was presented. The principles ot polarized-light-aided attitude determination were demonstrated and verified by simulation. A multi-module method for increasing the degree of observability were proposed. Federated kalman filtering was employed to implement the navigation algonthrn, The perfommnces of the navigation system with single-PL-module and multi- PL-module were respectively studied by Matlab simulating.The simulation results indicate that the degree of observablity and precision of the navigation system can be improved observablity, and the performance of the system can be improved rn：rre by using multi-polarized light module with line of sight non-parallel.
