摘　　要：GPS网布设过程中,如果测区面积较大、网形复杂,则经常需要计算各点的设站次数与各点相关的基线数目以便进行GPS网的图形设计和精度估算。而基线边数、观测时段数与接收机数量密切相关,本文通过分析得出了三者之间的关系的一般公式。In the process of GPS network layout, we often need to calculate the number of station points, and the number of the baseline related to points if measuring area larger and net-shaped complex, and then to design graphics and estimate accuracy. But the baseline edge numbers, observation session numbers are associated with the receiver numbers. This paper analyzes the relationship between them and obtained the general formula.
