Underwater cooperate target 3D positioning

In the sea trial of cooperate target testing,three dimensional positioning is needed.Based on comparision of characteristics of two typical positioning system,a 3D positioning system with three DGPS buoys for cooperate target is designed using synchronism time base,the positioning model is established.Sea trial results demonstrated that this system is capable of providing almost the same high-precision positioning for underwater target compared with DGPS,and also it has the feature of simple configuration and easy deploying.
