GPS卫星自动跟踪系统的地图数字化方案

A Map Digitisating Scheme for GPS Automatic Objectives Location

ＧＰＳ是一种以空间技术为基础的无线电导航系统，它的一个重要应用是自动多目标跟踪系统通过电子地图显示系统，实时监视目标位置及运动轨迹．地图的数字化方案对目标跟踪的准确性起着重要作用，对提高系统的综合性能也有重要意义．讨论适用于ＧＰＳ系统的地球平面投影模型，并提出一个可实施的数字化方案．

GPS is one kind of navigation system based on the space technology. One of its most important application is the Automatic Objectives Location System-by making use of computer mapping system, it keeps watching on the location and movement of objectives. The digitisating scheme is crucial to the accuracy of AOL. This paper discussed some global projection models appropriate to GPS and one applicable scheme was offered.
