Integrated vehicular navigation system based on the Beidou satellites

Various sensors, including electronic compasses, single axis gyroscopes, and the speedometer sensor, were used to develop an integrated vehicular navigation system based on an embedded system platform and the characteristics of the Beidou satellite system. The vehicle direction fusion algorithm and the vehicle position fusion algorithm utilize a Kalman filter algorithm to measure the vehicle's direction and position. A map matching method was used to give more precise map matching results and to stably interact with the Beidou satellite system. Vehicle location tests show that the integrated navigation system works well and makes the Beidou positioning system more practicable.
