| Abstract: | When Kalman Filtering is used in high kinematic GPS positioning, it is difficult to know the properties of kinematic noise and measurement noise. Therefore, the improved method of adaptive Kalman Filtering for GPS high kinematic positioning is proposed in this paper. The theoretical analysis and numerical results show that the method has better numerical stability, smaller memory, and stronger adaptability. |
