惯性器件与全球卫星定位系统(GPS)的组合导航成为目前车载导航的主流.无论在精度、性能、可靠性等各方面,GPS/DR组合导航系统都优于单独的GPS导航系统.在GPS信号丢失时,车载导航仪(GPS/GIS/DR)能利用陀螺自主导航,不间断提供导航信息并保持跟踪.
慣性器件與全毬衛星定位繫統(GPS)的組閤導航成為目前車載導航的主流.無論在精度、性能、可靠性等各方麵,GPS/DR組閤導航繫統都優于單獨的GPS導航繫統.在GPS信號丟失時,車載導航儀(GPS/GIS/DR)能利用陀螺自主導航,不間斷提供導航信息併保持跟蹤.

The integrated navigation of inertia elements and GPS is becoming the mainstream of vehicular navigation system.Compared with conventional GPS navigation system ,integrated GPS/DR navigation has better performances in terms of accuracy ,performance ,reliability etc.Vehicular navigation system (GPS/GIS/DR) can provide uninterrupted navigation information and keep tracing through gyroscope autonomous navigation when GPS signals are inaccessible.
