Bias Analysis of GPS/INS Integrated Navigation Under GPS Deception
To analyze the bias of GPS/INS integrated navigation under GPS deception,the loose coupled integrated navigation model and GPS spoofing model were established.On the basis of these models,the analytic relationship between deception time-delay and GPS deception bias was deduced by using the method of multidimensional Taylor analysis,and the effect of GPS deception bias on the locating result of integrated navigation was analyzed by Kalman recursion.The theoretical derivation and simulation analysis proved that: 1)GPS deception has an effective jamming effect on the locating result of loose coupled integrated navigation;and 2)The bias in integrated navigation at the present moment is affected by the former bias and GPS deception bias at the present moment synchronously,and the former bias has greater weight.
