To design a GPS/DR/DM integrated vehicle navigation system
after analyzing individual principles and characters of navigation and positioning system of GPS and DR
a kind of new cheaper GPS/DR/DM vehicle integrated navigation system has been designed and simulated with the integrated system by using the adaptive and extended Kalman filter
It is proved practical. The GPS/DR/DM integrated vehicle navigation system has been progressed and advanced more than the common navigation system both in reliability and precision. The GPS/DR/DM integrated vehicle navigation system is a more suitable vehicle navigation system.
