摘　　要：为了进一步研究全球卫星导航系统(GNSS)的应用和发展,通过介绍GNSS发展演变的过程,阐述各GNSS的技术进步,最后给出今后的发展趋势:GNSS业已经历40a的里程,从20世纪70年代中后期开始建设的美国全球定位系统和苏联格洛纳斯卫星导航系统,到21世纪初开始建设的中国北斗卫星导航系统和欧洲伽利略卫星导航系统;至2020年,以上4个GNSS将全部投入完全服务,从而构成包括全球系统、区域系统和星基增强系统在内的GNSS系统之系统。In order to further study the application and development of the global navigation satellite system(GNSS),the paper introduced the evolution process of GNSS,expounded its technologic progress,and gave the development trend:GNSS has evolved over 40 years,from the construction of the global positioning system(GPS)and the global navigation satellite system(GLONASS)in the mid-to-late 1970s,to the establishment of BeiDou navigation satellite system and Galileo navigation satellite system in the early 21st century;by 2020,all the above four GNSS would be put into full service,thus forming a general GNSS system including global system,regional system and satellite-based enhancement system.
