To bring about local navigation and position, it at least requires navigation signals from four pseudo satellite stations.
实现区域快速无源导航定位，需要至少四个伪卫星站提供的导航信号。
Considered a "pseudo satellite," Vulture may one day serve as a persistent intelligence, surveillance and reconnaissance (ISR) platform, or as an aerial node in a global communications network.
考虑到它是一颗“伪卫星”，Vulture可以作为一个情报、监视和侦查(isr)平台，或者作为一个全球通信网络的一个结点来服务。
Pseudo-time travel like this happens every day, with pictures taken by the Hubble Space Telescope, the mammoth Keck telescopes in Hawaii and the Chandra X-ray Observatory satellite to name just a few.
像这样的伪时间和旅行每天都在发生并被我们人类的探测工具（仅举几个例子，如哈勃空间望远镜、设置在夏威夷的一部庞大的凯克望远镜和钱德拉X射线观测卫星）拍摄下来。
The BD receiver can measure the pseudo distance between the satellite and the user, so that it can work in the passive positioning system.
