以一颗自主研发的GPS伪卫星为例,主要介绍了对于GPS伪卫星发射机的测试方法。首先介绍了伪卫星发射机的原理与设计以及各个主要模块。随后,逐一描述了对这些模块所进行的测试方法,并给出最终测试结果。最后,总结和分析了这些结果对伪卫星正常工作的影响。分析结果表明,该伪卫星的设计,达到了设计指标,满足了实用需求,其测试和分析方式具有普适性,能够应用于一般伪卫星的测试。

The testing methods of a GPS pseudolite which is developed and set up on ourselves is emphasized. First of all, the principle, design and the core modules of the GPS pseudolite are introduced. Then, the testing method for every module of the GPS pseudolite is described, and the results of the testing are demonstrated. At last, the impact of the results on the pseudolite is summarized and analyzed. These results reveal that the design of the pseudolite reaches the designed specification and can play a key role in developing the GPS pseudolite positioning system in the next stage.
