Study on the Key Technology of the Coastal Waterway Long-Distance Tide Extract and its Software Realization

In this paper, we developed a tide extraction software system which is based on GPS RTK / PPK and MRU (Motion Reference Unit) . Firstly, we analysis the quality control and the attitude correction which are the most important key technologies in this software . At the same time, the frame of the whole system, the computer environment, the software development tool are also analysised in detial in this paper. Finally, the stability and accuracy of this software system are verified by the experiment in Guangdong Yamen coastal waterway .
