Abstract

Causes and evaluation methods of time synchronization error of FOG SINS/GPS integrated navigation system were studied. In the evaluation method, by examining the quantitative relationship between time synchronization error of integrated navigation system and steady state estimation of longitudinal accelerometer bias by Kalman filter, an empirical formula was given. A semi-physical simulation was conducted with stable navigation data from a FOG SINS and simulated flight track. The simulation results indicate that the precision of proposed method is better than 80ms when the time synchronization error is 0.5s.

Key words： FOG; SINS/GPS; time synchronization; evaluation method; accelerometer bias estimation
