摘　　要：针对网络RTK在特殊环境中无法获取固定解的情况,提出一种基于虚拟站观测数据的控制点解算方法。通过Trimble Pivot软件生成虚拟观测数据,并利用TBC软件网解求出观测点位置。分析结果表明,虚拟观测数据各项质量评估指标均与真实观测数据相当,具有可靠性。另外,利用虚拟站点网解求出的控制点三维精度优于5 cm。Aiming at the situation that one may not obtain the fixed network RTK solution in some specific VRS envi ronment, this paper presents a control point calculating method based on the virtual station observation dala. The virtual refer- ence station observation data is generated by Trimble Pivot software, then the coordinate of observation point can be obtained within TBC software by baseline processing and adjusting together. The results show that the quality of the virtual reference station observation data is equivalent to the real station observation data and is reliable. In addition, the three-dimensional preci- sion of the control points obtained by using the virtual site network solution is better than 5 cm.
