A low cost differential GPS positioning system is introduced.The design schemes of the pseudo-range differential GPS posi-tioning system is based on the embedded device by using the microcontroller AT91M55800A and evaluation kit AT91EB55.The result proves that the positioning precision is improved to less than 5 meters with satisfied real-time capability.
