摘要
针对车载定位定向系统中存在的缺陷,设计了一种新的车载定位系统。完成了由低成本、高可靠性的捷联惯性参考系统与高分辨率里程仪组成的捷联惯性/里程仪组合定位、定向系统的方案设计及仿真计算。仿真结果表明,系统对姿态角、航向角等误差具有极高的在线对准及标定精度。组合系统无需停车,可进行零速校正。
Focused on shortcomings of vehicle-mounted positioning and orientation system, a new vehicle-mounted positioning and orientation system was designed. The scheme design and simulation of the hybrid system were finished which is composed of a strapdown inertial reference system and an odometer with low cost, high reliability and very high resolution. The simulation results show that the system is featured with high alignment precision for attitude angle error and heading angle error and period stopping for system verification is no longer required.
