| 摘 要： | 卫星导航产品在投入正式运行之前需要在地面上对其进行测试和校准,因此需要在地面建立模拟天上GPS卫星星座的测试环境,并通过修建伪卫星发射塔来发射类GPS卫星信号。测试环境中关于伪卫星发射塔站址选择问题是一个值得关注的硬件建设环节,它直接影响了系统的运行性能,本文通过对五个影响站址选择的因素进行论述,详细地说明了它们各自的影响特征,给出了相应的结论。

| Abstract: | Before application, the satellite navigation products should be tested and calibrated on the ground, so it is necessary to build a ground based pseudolites test system in order to simulate the GPS positioning constellation, and using pseudolite transmitters to send GPS-like signals. The purpose of this paper is to have an overall consideration to the five factors which influence the selection of pseudolites. Particularly we explain their characteristic of influence and give out the corresponding conclusion. |
