Title: Simulation of BDS /SINS Tightly Coupled Integrated Navigation System
Abstract: The improvement of positioning accuracy for BeiDou Navigation Satellite System is studied. In order to enhance the reliability,real- time and anti- interference of BDS,aiming at to solve the problem of poor navigation signal intervisibility,frequent lock- lose and low data updating rate in Beidou system,the aircraft tightly coupled BDS /SINS integrated navigation system is presented. The error models of BDS and SINS are analyzed,the state and measurement equation based on the pseudo- range and pseudo- range rate is built. The simulation results show that the tightly coupled integrated navigation system has a higher accuracy and reliability,and meets the demand of the aircraft navigation when the number of available navigation satellites is less than four. It makes up for the disadvantage of BDS.
