However, the positioning error of inertial navigation system is proportional to the carrier transit times, what is difficult to adapt to the development of underwater vehicle, so it needs other methods of navigation to aid. 然而,惯性导航系统定位误差会随着载体航行时间的增加而积累,因此难以满足水下载体对导航定位系统的要求,需要利用其它导航方式对其进行辅助导航。
This technology has been used in modern vehicle logistics management such as Vehicle tracking, Course planning and Travel navigation, Vehicle dispatching, Information management, Congestion control, Vehicle safety control and Emergency aid, etc. 将GPS技术应用于现代汽车物流管理,可以实现诸如车辆跟踪、出行路线的规划和导航、车辆调度控制、车辆安全保障、信息查询、话务指挥及紧急援助等功能。
