Research on the Method of Eliminating Gross Error of GPS Output Information

In GPS navigation positioning, the concept of measurement error is inevitable, and influencing the positioning accuracy of GPS and the integrated navigation. Therefore, this article focuses on the GPS output method for eliminating gross errors, and highlighted the three methods, namely, the gross error eliminated algorithm based on HDOP, the gross error eliminated algorithm based on speed detection and GPS gross errors processing based on HDOP and speed detection, and ends with measured data, as an example and then verifies the validity of these three methods.
