摘要
全球定位系统是美国布设的第二代卫星无线电导航系统。它是在地球上空布设24颗GPS专用卫星,卫星轨道即每时刻的精确位置由地面监控站测定,并通过卫星用无线电波向地面发播;地面上用GPS接收机同时接收4颗以上卫星信号,根据卫星的精确位署以求得地面点位置。结合GPS卫星定位技术在丹通路面工程中的实例,简要介绍GPS-RTK技术工作原理、技术特点。
GPS is the second generation satellite radio navigation system set by the United States, which is set 24 GPS dedicated satellites in the overhead of the earth, the accurate position of satellite orbit is measured by ground monitor station, and make use of the radio wave to send to the ground by means of satellite, GPS receiver simultaneous receive above 4 satellite signal in the ground, base on the accurate position of satellite to obtain ground position, combine with the example of GPS satellite positioning technology in the Dantong pavement engineering, operating principle and technical feature of GPS RTK is brief introduced.
