摘　　要：对测控设备进行精度鉴定是航空航天测控网建设的一个重要环节,本文针对飞机校飞GPS精度鉴定法中的坐标基准统一问题进行了探讨,重点介绍了全站仪法测量建立机载坐标系,并给出机载坐标系与地心坐标系,地心坐标系与站心坐标系,站心坐标与外测设备测量元素等坐标的转换关系,实现了测量元素和比对基准的统一。It is an important segment for the construction of the aviation survey and control net.This paper aimed at the problem of coordinate benchmark unify in the GPS precision judging with aircraft,which emphasized the method to establish the aircraft coordinate by using theodolite and gave the conversion relation between the aircraft coordinate and the core coordinate,further,the core coordinate and the stationary coordinate,the stationary coordinate and survey element of exterior survey equipment,realized the unify of the survey element and correlation benchmark.
