基于软件无线电的GPS信号接收系统

【摘要】随着无线电技术的发展，使其在越来越多的行业得到应用，尤其在导航技术方面的应用最为广泛。许多国家都在发展基于无线电技术的自己的导航系统，比如被人们熟知的美国的GPS、欧洲的Galileo、俄罗斯的GLONASS、中国的北斗，还有日本准备开发的准天顶卫星系统（QZSS），印度计划建立的IRNSS区域性卫星导航定位系统等等。有了这么多的导航定位系统，要实现用户定位还需一个必不可少的部分，那就是接收机。接收机是用户部分的核心，随着数字信号处理技术的发展，卫星信号的接收越来越趋向于采用软件无线电的方法来实现。本文介绍的就是基于GPS导航系统的无线电信号接收系统。

With the development of radio technology, it applied more and more industries, especially in navigation technology. Many countries are developing their own technology-based radio navigation system, such as is known in the United States GPS, Europe＇s Galileo, Russia＇s GLONASS, China＇s Compass, as well as Japan prepared to develop the Quasi-Zenith Satellite System （QZSS）, India plans to set up IRNSS regional satellite navigation systems, etc. With so many navigation and positioning system to locate the user needs to achieve an essential part of that receiver. Receiver is the user part of the core, with the digital signal processing technology, satellite reception tends to be more use of software radio methods. This article is radio signals receiver based on GPS navigation system
