Abstract: | In this paper, the advantages and development of GPS applied in a space vehicle are introduced first. Then, the software employed to calculate the applied altitude of GPS in a space vehicle is explained. The detailed software flowchart is also given, and the process of choosing used GPS satellites is described in detail. In order to study the receiving condition in a space vehicle, we also make a simulating calculation with our software. The results of receiving GPS satellites over a certain place are given. The paper has not only the value for using GPS in a space vehicle, but also the significance for an aircraft whose navigation system is GPS |
