多系统兼容卫星导航接收机关键技术概述

摘要

The global navigation satellite system is one of the fastest and most popular hot spots in the field of information technology.With the continuous development and improvement of the navigation satellite, the application of multiple system compatible satellite navigation system has become the trend of the development of the satellite navigation.In the design of multiple systems combined GNSS receivers, the space-time conversion algorithm, fast satellite selection algorithm and the integrity detection of the navigation system seriously affect the performance of the navigation receiver.Based on some key technologies in the design of multiple systems combined GNSS receivers, this paper expounds the development status of the current multiple systems combined GNSS receivers, and prospects the research emphases of the future multiple systems combined GNSS receivers.%随着各导航卫星的发展与完善,多系统兼容卫星导航系统的应用成为卫星导航发展的趋势,在对多系统兼容卫星导航接收机的设计中,导航系统的时空转换算法、快速选星算法、系统完好性检测等技术严重影响着导航接收机的性能.文中针对多系统兼容接收机设计中的一些关键技术,阐述了当前多系统兼容接收机的发展状况,并对未来多系统兼容接收机的研究重点进行了展望.
