摘要
GNSS PPK(Post Processing Kinematic)技术属动态后处理技术,不受电台无线电传播距离的限制,有效作用距离可以达到80 km。本文提出了GNSS PPK技术在疏浚与吹填工程的应用,包括控制测量、摄影测量、三维水深测量和海上高程异常测量,解决了疏浚工程测量中的多个问题,在今后的疏浚与吹填工程测量中具有推广价值。
GNSS PPK(Post Processing Kinematic)is a dynamic post-processing technique,which is free from the restriction of radio transmission distance,and guarantees the effective distance of 80km.The application of GNSS PPK technique in dredging and reclamation projects is introduced in detail,including control survey,photogrammetry,3D bathymetry and sea elevation anomaly survey.The research results solve the problems existed in the dredging survey,and are worthy of promotion in the dredging and reclamation projects.
