| 摘 要： | 对城市老控制网的改造，通常是布设GPS网，为了能充分利用原有的测量资料，又要保证控制网的精度，有时需要对GPS控制网加入常规观测值，文中主要讨论在GPS控制网中加入常规观测值对控制网精度的影响，通过实例证明，适当加入常规测量值可提高控制网的精度．

| Abstract: | To reconstruct the old geodetic chain of the city, usually we establish the GPS geodetic chain. For the sake of using the existed measured data adequately and ensuring the precision of the GPS geodetic chain, sometimes we add the routine measured value into the GPS geodetic chain. This paper mainly discusses the effect on the precision of the GPS geodetic chain after adding routine measured value. The experience proves that the precision of the GPS geodetic chain can be improved by adding the routine measured value. |
