摘要
针对北斗导航定位系统的特点及存在的问题。为改善其在车辆导航定位中的性能,以低成本无陀螺DR作为其辅助定位方式,设计北斗/DR组合导航系统,并根据该系统的特点,给出合适的卡尔曼滤波算法。仿真结果表明,设计的北斗/DR组合导航系统在精度和可靠性方面,有明显改善,可满足车辆导航定位的要求。
Aiming at characteristics and problems of BEIDOU navigation and location system, proposes a low-cost integrated navigation system to improve its performance in vehicle navigation and orientation. Regarded low-cost no-gyroscope DR as its assistant position system, and in response to the system＇s characteristics, brought forward the suitable Kalman filtering algorithm. Simulation result shows the system＇s performance has advanced obviously in accuracy and reliability, and can meet vehicle navigation and position requirements.
