说明：  GPS315使用手册：作为尖端技术GPS，能方便快捷性地测定出点位坐标，无论是操作上还是精度上，比全站仪等其他常规测量设备有明显的优越性。随着我国各地GPS差分台站的不断建立以及美国SA政策的取消，使得单机定位的精度大大提高，有的已经达到了亚米级精度，能够满足国土资源调查、土地利用更新、遥感监测、海域使用权清查等工作的应用。
(GPS315 User' s Guide: cutting-edge technologies as GPS, can be easily and quickly measure of the point coordinates, whether operational or accuracy than conventional total stations and other measuring equipment has obvious advantages. With differential GPS stations around the continued building and the cancellation of the U.S. policy of SA, making stand-alone greatly increased the accuracy of positioning, and some have reached level yami accuracy, able to meet the national land resources survey, land-use updates, remote monitoring, waters such as the right to use the work of the application inventory.)
