| Abstract: | Aimming at latest progress of the ocean-over vertical datum connection,this paper introduces several vertical datum connection methods,and their advantage and weakness,and evaluates the application scope of them.The preliminary test shows that the methods of vertical datum connection can satisfy the accuracy of third order levelling in 10km.For longer distant application,the method of vertical datum connection needs more researches. |
