摘　　要：由于现地观测条件限制,GNSS天线无法架设在需要观测的目标点上,无法实现精确对中观测目标所对应的地面点中心,此时就需要进行GNSS偏心观测。文中从解决卫星天线定位定向的工程出发,研究GNSS偏心观测三角形法和经纬仪交会法计算归心元素。依据模拟实测计算结果以及实际卫星天线定位定向的结果,分析了两种方法的优缺点。Due to the restriction of field observation conditions,GNSS antenna cannot be set up on the target point which needs to be observed,and it is impossible to implement the precise center of ground points in the corresponding observation targets.At this moment,GNSS eccentric observation is necessary.This paper,starting from the solution of antenna positioning and orientation,studies the GNSS triangle method and the theodolite intersection method to calculate the elements of center.And also,this paper analyses the advantages and disadvantages of this two methods according to the simulated calculation results and the actual results of satellite antenna positioning and orientation.
