| Abstract: | 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. |
