“ 虚拟卫星”是一套全新理念的卫星资源整合系统，用户通过虚拟卫星定购数据时，无需考虑卫星本身的类型，只是向该系统提供分辨率和时相参数要求，虚拟卫星就可以将目前所有的卫星资源进行整合，向用户提供标准化数据产品以及全面的解决方案。
Pseudolites studied in the paper work at the virtual satellite pattern. Their main function is to simulate the satellite signal from the really satellite on the satellite orbit through changing code phase, Doppler shift, carrier and signal-to-noise ratio.
本文研究的伪卫星是工作在虚拟卫星模式下的。

再看看谷歌地球吧，它能把世界上任何一个角落的卫星图像放到你的桌面上，让用户把虚拟数据和现实世界中特定的一点联系起来。
Or consider Google Earth, which puts satellite images of the whole world on your desktop and allows users to link online data with specific physical locations.
