At the 20,000 -kilometer GPS satellite, when the earth rotates for a week for stars, they have run around for two weeks, that is, when the satellite runs around for a week is 12 stars. In this way, for ground observer, the same GPS satellite will be seen 4 minutes a day in advance.
The number of satellites above the horizon change changes with the time and place of time and place. At least 4 can be seen, and up to 11 can be seen.
When using GPS signal navigation positioning, in order to solve the three -dimensional coordinates of the measurement station, 4 GPS satellites must be observed. This method is called "positioning constellation". The geometric location distribution of these four satellites in the observation process has an impact on the accuracy of positioning. At a certain place, no accurate point coordinates cannot be measured. This time period is called "gap segment". However, this time gap segment is very short, and it does
