GNSS PPK动态后处理测量作业模式与应用分析

Operation Mode and Application Analysis of GNSS PPK Dynamic Post-processing Measurement

PPK测量作为GNSS动态测量后处理技术,其作业过程不需要流动站与基准站之间建立实时通信链路,有效克服了RTK测量需要信号强、通信链路稳定的缺点。本文在介绍PPK测量作业模式及数据处理过程的基础上,探讨PPK作业过程中的注意事项,通过实例分析PPK作业模式的影响因素及精度,为PPK测量在工程中的应用提供了借鉴。

PPK measurement as GNSS dynamic measurement post-processing technology, its operation process does not need to establish a real-time communication link between the mobile station and the reference station, which effectively overcomes the shortcomings of RTK measurement that requires strong signals and stable communication links. Based on the introduction of PPK measurement operation mode and data processing process, this paper discusses the matters needing attention in the process of PPK operation, and analyzes the influencing factors and accuracy of PPK operation mode through examples, which provides a good reference for the application of PPK measurement in engineering.
