GPS测量技术在核电站高精度测量控制网中的应用与探讨

Application and investigation on GPS measurement technology in high precision survey control network of nuclear power station

文章结合GPS在红沿河核电站一期1#、2#机组次级控制网工程中的实践,通过应用GPS基线向量精度的检核、足够数量的接收机进行同步对向观测、卫星数量的捕捉、采用双差观测等关键技术,证明GPS能够满足建立核电站高精度控制网(点位中误差≤±2mm)的要求。

This article proves that GPS could meet the need of building high precision survey control network of nuclear power station(mean square error of a point≤±2mm)combing with practice of applying GPS in secondary control network project of 1# and 2# units of Hong Yanhe nuclear power station.The project used some key technologies such as GPS baseline vector precision check,reciprocal observation at the same time using enough receivers,capture of satellite amount,double difference observation and so on.
