【摘要】:GNSS PPK(post processing kinematic)技術(shù)屬動(dòng)態(tài)后處理技術(shù),不受電臺(tái)無(wú)線電傳播距離的限制,有效作用距離可達(dá)80 km。為解決沿海長(zhǎng)航道水深測(cè)量需在海上設(shè)置定點(diǎn)驗(yàn)潮站的難題,提出基于Hypack 2014的GNSS PPK三維水深測(cè)量方法。該方法無(wú)需進(jìn)行水位提取與水位擬合,提高了水深測(cè)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(kāi)發(fā)。介紹GNSS PPK定位原理及GNSS PPK三維水深測(cè)量工作原理,闡述基于Hypack 2014的GNSS PPK三維水深測(cè)量的實(shí)施方法,在沿海長(zhǎng)航道水深測(cè)量方面具有推廣價(jià)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.
