摘　　要：给出了矩阵体积法的原理和方法,并使用矩阵体积法研究了水下差分GPS定位中设计矩阵的态性,导出了星形空间网中设计矩阵的体积与观测向量高度角参数的函数关系式,为研究星形空间网图形强度提供了数学模型。In this paper, the principle and approach of Matrix Volume Method are introduced firstly. And the design matrix of underwater DGPS wtor 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.
