基于CORS的PPK技术在外业测量中的应用

The PPK Technology Base of CORS in the Application of Survey

介绍基于CORS系统的PPK技术和相关操作及数据后处理流程。在网络RTK不能够正常作业的情形下,可以采用PPK技术作为有效的补充手段。结合像控外业测量实例,探讨了此方法的可用性,并分析了测量成果的内外符合精度,以及作业应该注意到相关问题。

The paper describes the CORS system PPK-based technology, and related operations and data processing. At the situation of network RTK in abnormal operating, PPK can be used as an effective supplementary means of technology. With examples of outwork field measurement, the availability of this method is discussed, and the result of internal and external line measurement accuracy is analyzed also as well as some related issues of operation that should be noted to.
