| Abstract: | While GPS is practical currently, it needs more than 4 observed GPS satellites to work. This paper presents an integrated navigation system based on the information provided by digital map, including two-satellite positioning based on the information provided by the digital map and DR system and its filtering algorithm. Experiments show that the integrated navigation system can provide precise positioning result and enhance the adaptability of vehicles in the complex environment of cities. |
