This paper discusses the data processing in details in WADGPS system,and introduces a system that utilizes ordinary single frequency GPS OEM and Beidou receiver to collect GPS and DGPS data and implement the WADGPS algorithm.The application of this scheme to the user GPS can improve the GPS accuracy from the original 25 m GPS error to 3 m in horizontal direction,4 m in the elevation direction.The engineering practice proves that this scheme is feasible and easy in implementation as well as a steering means with high precision.
