精密单点定位技术在海上工程中的应用

Research on Precise Point Positioning Technology Application in Engineering Practice

结合海上科研工程实践,对GPS精密单点定位模型及数据处理方法进行研究,并采取陆上静动态定位和海上动态定位试验进行了精密单点定位精度统计和分析。结果表明:在超出常规差分定位基线长度限制的广阔海域,采用精密单点定位技术可实现亚米级实时动态定位,为海上高精度实时动态定位应用提供了技术依据。

Based on scientific research and engineering practice at sea, this paper discusses GPS precise point positioning model and data processing method, countes and analyses it＇ s precision in captive and dynamic positioning test on land and dynamic positioning test at sea. The results show that： submeter-level real time dynamic positioning can be achieved with precise point positioning technology, at vast sea area which is over limit of routine differential positioning baseline length, and that provides technical basis to application of high precision real-time dynamic positioning technology at sea.
