GPSPPK技术在像控点测量中的应用及精度分析

摘要

PPK is a kind of GPS position technology that utilize carrier -phase to calculate data of post -processed differential correc-tion.It doesn’t need chain of data and has much more flexibility .In addition, GPS PPK can play a significant role while communica-tion is in restriction.Moreover, it actually makes up defects of RTK .The thesis takes advantage of a real case to introduce application and analysis of accuracy on GPS PPK in the photogrammetric control point surveying .%PPK是利用载波相位进行事后差分的GPS定位技术，不需要数据链，具有较强的灵活性，在通信条件受到限制的情况下能发挥巨大的作用，很好地弥补了RTK的不足。本文结合实际案例介绍了PPK技术在像控点测量中的应用及精度分析。
