%X 目前国内水电站施工测量控制网大都基于全球定位系统(global positioning system, GPS)系统建设，伴随着我国自主建设的北斗三号卫星导航系统(Beidou-3 satellite system, BDS-3)逐步完善，这为水电站建设行业摆脱GPS系统提供了可能。本文根据某水电站建设重点项目为例，以GAMIT专业基线解算软件分别处理北斗数据与GPS系统数据，在基线解算精度，测站点坐标平差精度进行比较分析。研究表明：基于北斗卫星系统的控制网解算精度与GPS系统的控制网解算平差精度处于同一水平，在观测条件优良的情况下甚至优于GPS系统。充分证明了北斗卫星导航系统在水电站施工控制网建设中的适用性与可行性。<br />
At present, the domestic hydropower station construction measurement and control networks are mainly based on the global positioning system (GPS) system, along with the gradual improvement of China's independently constructed Beidou-3 satellite navigation system (BDS-3), which provides a possibility for the hydropower station construction industry to get rid of the GPS system. This provides a possibility for the hydropower station construction industry to get rid of the GPS system. In this paper, according to a key project of hydropower station construction as an example, GAMIT professional baseline solving software handles BeiDou data and GPS system data respectively, and compares and analyses the baseline solving accuracy and the leveling accuracy of measuring station coordinates. The study shows that the accuracy of control network solving based on the BeiDou satellite system is at the same level as that of the GPS system, and even better than that of the GPS system under excellent observation conditions. It fully proves the applicability and feasibility of the BeiDou satellite navigation system in the construction control network of hydropower station.
