| 摘 要： | 从影响GPS定位精度的因素入手,对建立差分GPS(DGP)基准站及基准站地心坐标(基准坐标)的测定,作了较详细的研究.为了解决异地使用中,DGPS不便于用联合观测网站测定基准坐标的问题,根据多次实际测量的结果,提出了用直接测量法确定基准坐标更为方便、有效.

| Abstract: | The establishing of GPS (DGPS) reference station and the identifying of ground coordinates (reference coordinates) in terms of those factors effecting accuracy are investigated. Actually, there are difficulties in determining the reference coordinates through cooperation of observation station locating in different places. To solve the problem, a new solution is proposed based on large numbers of practical measurements. And the result proves that the solution can efficiently identify reference coordinates in an easier way. |
