摘要
虽GNSS导航定位技术的发展给人们带来极大便利,但在一些现代应用中已逐步呈现出明显的不足,如在高楼林立的城市、室内(人们生活、工作和娱乐的场所)等特殊区域,卫星信号衰减严重甚至完全接收不到,然伪卫星技术的出现弥补了上述的不足。在对伪卫的简要介绍基础上,系统地论述了伪卫星技术的三种定位方式,通过仿真实验数据对该技术进行精度分析,针对伪卫星的关键技术给出了相应解决方案,最后列举了其在各领域中的应用。
Though the GNSS navigation and positioning technology brings great convenience to people,it presents the obvious shortages in modern application gradually.The attenuation is so worse that the receiver can’t receive the signal from satellites in some special areas where people live and work,but the technology of pseudolite has made up for these weak spots.This article explained the origin and concept about the pseudollite,and then described three pseudollite methods.Through simulation experiment data analyzed the technique’s precision,For the key technology of pseudolite gives the corresponding solutions,finally illustrates its application in various fields.
