摘　　要：以松辽盆地西缘开展的石油重力勘查为例,分析了实时精密单点定位技术实施控制测量的全过程以及精度评价方法。利用Trimble R10型测量仪在测区进行了实时精密单点定位测量,在已知GNSS控制点进行了观测试验,获取了3 d不同时段共38个观测数据。研究表明:该技术测量精度(平面中误差为±0.012 m,高程中误差为±0.035 m)满足石油重力勘查控制测量精度要求,避免了大范围GNSS控制网联测,经济可靠。Taking the petroleum gravity exploration carried out in the western margin of the Songliao Basin as an example,the whole process of implement control measurement by using real-time precision single point positioning technique and the precise evaluation method are introduced.The Trimble R10 measuring instrument is used for real-time precision single point positioning measurement in the measuring area,the observation test is carried out at the known GNSS control points,and 38 observation data in different time periods of 3 days are obtained.The precise evaluation results show that the accuracy (plane error is ±0.012 m,elevation error is ±0.035 m) can meet the measurement accuracy requirements of petroleum gravity survey control,besides that,the large-scale GNSS control network can be avoided,and economical of the real-time precision single point positioning technique is reliable.
