高中地理教材中,涉及“全球定位系统”这一知识:“大纲”教材在选修第二册有专节介绍;“课标”教材则有专门一个选修模块。它们都以“3S”技术(即RS、GIS、GPS)的结构予以介绍。实际上,GPS只是全球卫星定位导航系统的一个具体版本,此外还有俄罗斯的“全球卫星定位导航系统”(简称GIS),以及研制中的欧洲的“伽利略”全球卫星定位导航系统,等等。伴随着众多卫星定位导航系统的兴起,现全球卫星定位导航系统有了一个全新的称呼GNSS。也就是说,以后严格意义上“3S”并列的应是RS、GIS、GNSS。本文将对欧洲“伽利略”计划作一介绍,作为对教材的一个补充资料。
High school geography textbooks, related to “Global Positioning System ” This knowledge: “Outline ” textbook in the second edition of the elective has a section introduces; “Course standard ” textbook has a special elective module. They are all introduced in the structure of “3S” technology (ie RS, GIS, GPS). In fact, GPS is only a specific version of the Global Positioning System (GPS), in addition to the Russian “Global Positioning System” (GIS) and the European “Galileo” Global Positioning System ,and many more. With the rise of many satellite positioning and navigation systems, the global positioning satellite navigation system now has a brand new title GNSS. In other words, in the strict sense of the “3S” side by side should be RS, GIS, GNSS. This article will introduce the European “Galileo” project as a supplementary material to the textbook.
