【Abstract】 The surveying precision of GPS net has a relationship with surveying precision of the baseline in net and the construction of the net. Precision of the baseline measurement depends on conditions surrounding the two points in the baseline ends and the length of time surveying the baseline. This paper discusses the above problems of little GPS net through an example.更多还原
