| 摘 要： | 全球导航卫星系统已经引起了测量、测地、导航和其他与定位相关的学科的革命，但是卫星导航定位系统有两个内在的弱点：信号衰减和定位结果依赖卫星的几何布局。因此在比较苛刻的观测环境下，系统的表现明显降低。伪卫星就是为了解决这个问题而引入的。本文讲述了伪卫星发展的相关历史和近来伪卫星定位方面的一些成就，并提出了现存的技术问题。

| Abstract: | Global navigation satellite systems have been revolutionizing in surveying, geodesy, navigation and other position fields. However, there are two intrinsic shortcomings in such satellite-based positioning systems: signal attenuation and dependence on the geometric distribution of the satellites. Consequently, the system performance can decrease significantly under some harsh observing conditions. To tackle this problem, using of pseudo-satellites has been developed. In this paper, the history of pseudolite development and recent progress in pseudolite-based positioning are reviewed, meanwhile, its current technical issues are discussed. |
