Analysis and Implementation of GPS Dynamic Positioning Filtering Algorithm

摘要：

In order to solve the problem that the accuracy of low-cost GPS module for dynamic positioning is generally low, filtering theory is applied to the GPS dynamic positioning system. In this paper, the principle of GPS dynamic positioning is introduced, the filtering model and algorithm of Kalman filter are composed, and the filtering formula is deduced. Then processed experiment by vehicle to verify the filtering theory. In the experiment, two OEM boards of different precision are selected, then compare the low-precision data after filtering with the data of the h igh-precision benchmark OEM board. The result of th e experiment shows that, accuracy of d ynamic positioning after filtering is im proved significantly. And through this paper, a new reference solution for precision GPS dynamic positioning by using low-cost OEM boards is provided.
