全球定位系统(Global Positioning System,简称GPS)是综合了航空、无线电、计算机、卫星通信等高技术的导航系统.它能在全球范围内,全天候地连续提供极高精度的三维坐标、速度和时间等信息.该系统由空间部分、地面控制部分和用户设备三部分组成.其中,用户设备包括GPS卫星信号接收器和数据处理器,用户可以用接收来的卫星信号确定自己在陆地、海上或近地空间(海拔2万米以下)的位置,实现导航;用户也可利用GPS系统的时间部分,达到守时功能,华诚卫通公司的工程师们在GPS领域已进行了几年的探索,积累了一些成功的经验.现就GPS技术在我国的应用状况作一展望,以供业界朋友和其他各行人士参考.
Global Positioning System (GPS) is a high-tech navigation system that integrates aviation, radio, computer, satellite communications, etc. It can provide extremely high-precision three-dimensional coordinates, speed and time Etc. The system consists of a space part, a ground control part and a user equipment, wherein the user equipment comprises a GPS satellite signal receiver and a data processor, and the user can determine whether he is on land, at sea or near by using the received satellite signal Space (below 20,000 meters) position, to achieve navigation; users can also use the time part of the GPS system to achieve punctuality, Huacheng Weicheng company engineers in the field of GPS has been a few years of exploration and accumulation Some successful experience is now on the application of GPS technology in our country look forward to for the industry friends and other public figures for reference.
