 借鉴目前常用车辆导航系统中GPS实时信息在数字地图上的匹配算法和经验,分析了我国"北斗一号"导航系统现状,针对"北斗一号"导航系统定位特点以及道路复杂等因素而可能造成直接定位不准确的问题,提出了基于"北斗一号"实时定位信息进行地图匹配的可行性,并初步构想了地图匹配的算法,从而提高导航监控的准确性。 更多还原

【Abstract】 This text made reference to the map-matching calculate way and experienced about the GPS in use of vehicle navigation system.Analyzed the present condition of "Beidou I",aimed at the Positioning traits,complicated road and other factors lead to rough result,got the feasibility in foundation of current positioning information came from Beidou I,and speculated the calculate way of map-matching,well raised the accuracy of navigation and supervision. 更多还原
