如今,人们的生活已经离不开卫星导航定位系统,不夸张的说,上至航空航天,下至工业、渔业、农业生产和日常生活,全球卫星导航定位技术已经是无所不在。说起卫星定位,就离不开GPS和中国的北斗。偶然“出生”的GPS1957年10月4日,前苏联发射了全世界第一颗人造地球卫星,开创了人类的空间世纪时代。美国对此密切关注,有一位名叫比尔.盖伊和数学家和一位叫乔治.威芬巴赫的物理学家,他们在霍普斯金的应用物理实验室里发现了一个现象,那就是这颗卫星的频率出现了偏移,经研究发现是相对运动引起的多普勒频移效应。这两位科学家对此进行了实验研究,发现
Today, people’s lives are inseparable from the satellite navigation and positioning system, and it is no exaggeration to say that the global positioning technology for satellite navigation and navigation has become ubiquitous from aerospace to industrial, fishery, agricultural production and daily life. Talking about satellite positioning, it can not do without GPS and China’s Beidou. Occasional “born ” GPS On October 4, 1957, the former Soviet Union launched the world’s first man-made earth satellite, creating a century of space for mankind. The United States pays close attention to this issue. One man named Bill Gay, a mathematician, and a physicist named George Wiebandbach, who discovered a phenomenon in Hopkins’ Applied Physics Laboratory, The frequency of the satellite shifted, the study found that relative motion caused by the Doppler shift effect. The two scientists conducted an experimental study, found
