A Differential Dynamic Positioning Algorithm Based on GPS/Beidou

There are mainly two kinds of satellite positioning products at present as follows: a kind of high precision and high cost positioning equipment is difficult to have been applied in larger-scale, while another kink of low cost equipment have been applied in larger-scale is low precision. This paper includes a differential dynamic positioning algorithm based on GPS/Beidou which realizes middle precision based on low cost equipment. The development of this equipment has significance in vehicle navigation system.
