Filter Design of Bionic Polarized-light Integrated Navigation System Based on Federated Filter
This article focuses on the problem of unknown environment and multi-source interference in field ground navigation systems,and designs a biomimetic polarization integrated navigation system with environmental adaptability and anti-interference ability.Firstly,the bionic polarized-light navigation technology is introduced to form the bionic polarized-light/MIMU/GPS integrated navigation system without reset federal filter structure,and the interference model of each subsystem is established.Secondly,in order to improve the applicability and anti-interference ability of the system for dynamic unknown environments,utilizing the superior fault tolerance ability of federated filters,intelligent switching schemes for several combination modes are designed to effectively detect and isolate GPS interference sub-systems,and achieve the reconstruction of available systems.
