一种专门为中国用户研制的导航型电子地图化的全球卫星定位系统(GPS)定位 接收机,已由北京市赛达科贸公司研制成功。 GPS全球卫星定位系统被称为本世纪继阿波罗登月计划、航天飞机计划之后的第三项庞大的空间计划。GPS技术的出现,从根本上解决了人类在地球上的导航和定位问题。目前,国际上研究、生产GPS产品的机构和厂商已不下百家,并已开始涌入我国市场。 但国内用户,特别是陆地用户在使用国外GPS产品时感到极不方便。GPS显示的定位数据都是在其他国家大地坐标系统下的经伟度值,文字显示也都是英文显示。 A navigation-oriented global positioning satellite system (GPS) receiver specially developed for Chinese users has been successfully developed by Beijing Saida Electronics Co., Ltd. The GPS Global Positioning System (GPS) is known as the third massive space program in the 21st century following the Apollo moon landing program and space shuttle program. The advent of GPS technology has fundamentally solved the problem of mankind’s navigation and positioning on the earth. At present, there are no fewer than 100 institutions and manufacturers in the world for researching and producing GPS products and have already started to pour into the Chinese market. However, domestic users, especially land users, feel extremely inconvenient when using foreign GPS products. GPS positioning data are displayed in other countries under the Earth coordinate system by the great value, the text display are also displayed in English.
