In the 1970s, Lu, Hai, and Air Force jointly developed a new generation of global positioning systems. The main purpose of GPS was to provide real -time, all -weather and global navigation services for Lu, Hai, and Air Force. After more than 20 years of research experiments, such as more than 20 years of research experiments, such as more than 20 years of military purposes, it cost $ 30 billion. By 1994, 24 GPS satellite constellations with a global coverage rate of 98%had been completed. GPS has gone through the first and second generation, and now it has been upgraded to the third generation to maintain its hegemonic position in the navigation positioning system. From the current point of view, GPS is the most accurate and most widely covered navigation in the world. GPS.
The initial GPS plan was formulated under the leadership of the United States United Planning Agency, which placed 24 satellites on three orbits of each other. There are 8 satellites on each orbit, and 6-9 satellites can be observed on the earth. In this way, the coarse code accuracy can reach 100m and the precision accuracy is 10m. Due to the compression of the budget, the GPS plan had to reduce the number of satellite launch and changed to distributed 18 satellites on the 6 orbit of 600. However, this plan could not guarantee the reliability of satellites. The last modification was carried out in 1988: 21 working satellites and 3 spare satellites worked on 6 orbits of 600. This is also the current way of working in GPS satellite
