【摘要】:GNSS PPK(post processing kinematic)技術屬動態(tài)后處理技術,不受電臺無線電傳播距離的限制,有效作用距離可達80 km。為解決沿海長航道水深測量需在海上設置定點驗潮站的難題,提出基于Hypack 2014的GNSS PPK三維水深測量方法。該方法無需進行水位提取與水位擬合,提高了水深測量精度;且采用現(xiàn)有商業(yè)軟件TBC和Hypack,避免了繁瑣的二次開發(fā)。介紹GNSS PPK定位原理及GNSS PPK三維水深測量工作原理,闡述基于Hypack 2014的GNSS PPK三維水深測量的實施方法,在沿海長航道水深測量方面具有推廣價值。
[Abstract]:GNSS PPK(post processing kinematic) is a dynamic post-processing technology, which is not limited by radio transmission distance. The effective working distance can be up to 80 km. In order to solve the problem of setting up fixed tide stations at sea in order to solve the problem of water depth survey in coastal long channel. A GNSS PPK 3D bathymetric method based on Hypack 2014 is proposed, which does not need water level extraction and water level fitting, and improves the precision of bathymetric measurement. The existing commercial software TBC and Hypackare used to avoid the complicated secondary development. The principle of GNSS PPK positioning and the work principle of GNSS PPK 3D bathymetry are introduced. This paper expounds the implementation method of GNSS PPK 3D bathymetry based on Hypack 2014, which is worth popularizing in coastal long channel bathymetric survey.

【正文快照】: 對于沿海長航道水深測量,當測區(qū)超出岸邊水位站有效控制范圍時,可在海上設立臨時水位站(修建驗潮站、拋壓力式驗潮儀)、潮位推算,或直接進行GPS RTK三維水深測量。但海上修建驗潮站的難度大、成本高,因此較少采用;拋壓力式驗潮儀則會面臨驗潮儀丟失或由于儀器在海底滑動導致采,
