摘　　要：GPS定位技术具有全天候、高效率、高精度且GPS点间无需通视、作用距离远等特点,在控制点无法架设GPS观测时,可采用偏心观测。介绍了从实用角度出发,在高精度GPS偏心观测中归心元素的测定方法,并介绍了其应用与其分析。The GPS location technology has the characteristics of all the climate, high efficiency, high precision, needing no vision between the points of the GPS, and long distance. The eccentric observing method of the GPS could be taken as the GPS could not be supported to observe at the control site. This paper introduces the measure method of the reduction of factors, in the eccentric observation of the GPS from the angle of actual use. Also it introduces its usage and analysis.
