| Abstract: | In this paper,the principle and approach of Matrix Volume Method are introduced firstly.And the design matrix of underwater DGPS vector representation positioning model is studied by using this method.Furthermore,the volume of the design matrix was deduced to be a function which variables are the space network structure parameters.The function provides a mathematic model for studying star three-dimensional network's anti-jamming capability of Underwater DGPS. |
