摘要: 针对城市连续运行参考系统(CORS)下网络实时动态(RTK)在特殊环境中无法获取固定解的情况,提出了基于虚拟观测数据的后处理解算方法,探讨了基于Trimble Pivot platform软件生成虚拟观测数据和利用TBC软件网求解观测点位置的解算流程和步骤,分析了虚拟观测数据的使用对解算精度的影响．实例分析结果表明,虚拟观测数据各项质量评估指标均与真实观测数据相当,且通过实际工程进行了验证,确定了虚拟观测数据具有一定的可靠性．Abstract: In view of the fact that network RTK under CORS system can not obtain fixed solution in special environment, a post-processing solution method based on virtual observation data is proposed. The process and steps of generating virtual observation data based on Trimble Pivot platform software and calculating the position of observation points by TBC software network are discussed, and the process and steps of calculating the position of observation points by TBC software network are analyzed. The result of SYCORS example analysis shows that the quality evaluation indexes of virtual observation data are equivalent to the real observation data, and the virtual observation data is verified by practical engineering, which confirms that the virtual observation data has certain reliability.
