Abstract

Analyze the time synchronization problem of the GPS/INS Integrated Navigation System. The relationship between time delay and data fusion filter performance is analyzed in the GPS/INS Integrated Navigation System on the basis of Kalman Filter algorithm. Design the time synchronization system on the basis of the 100Hz data collection signal to generate the pseudorange collection signal. The system gets the pseudorange collection signal and INS data collection signal together to solve the problem of time synchronization. The data collection system and time synchronization system can also correct the error of timing and crystal frequency compared with the traditional time synchronization system. The simulation results verify that the time synchronization system can improve the position accuracy on complex dynamic situation and reduce the estimation error of the Kalman filter.
