GPS can provide continuous heading information, but the accuracy is easily affected by velocity and shelter from buildings or trees. For vehicle systems, we propose a low-cost angle update algorithm. Based on GPS/INS integrated navigation kalman filter, add to measurement vector, establish its error model. The experiment results show that this algorithm effectively improve of angle.
