Aiming at drawbacks of present vehicle navigation systems

a low cost single gyroscope

and single accelerometer DR scheme with tilt compensation is proposed.Taking advantages of both DR and GPS/BD systems

an integrated navigation scheme is accomplished through hardware and software design to improve and perfect navigation characteristics.City road experimental results show that the integrated navigation system can meet the requirements of the vehicle navigation and achieve high positioning precision especially under the circumstances of mobility

ramp and signal blocking areas

which has certain reference meaning for vehicle navigation under complex road condition.
