| Abstract: | The space coverage property of GPS constellation is studied. The requirements of minimum coverage for normal system operation is illustrated principally. Taking account of the specialty,a definition for coverage is given and the corresponding judgement is reduced. Based upon above,the simulation test is designed for GPS constellation and the space coverage results are also acquired. Finally, the conclusion is given and the analysis is performed. |
