摘　　要：针对目前导航系统的不足,提出了一种带倾角补偿的低成本单陀螺仪单加速度计航位推算(DR)方案。结合DR与GPS/BD系统的特点,通过软硬件设计,实现了GPS/BD-DR组合导航方案,提高并完善了导航性能。城市路况实验结果表明:该组合导航系统能够满足车载导航的基本需求,尤其在灵活移动、多坡道及信号盲区环境下具有较高的定位精度,对城市复杂路况导航具有一定的参考意义。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.
