Constellation Satellite Number _ Constellation Satellite Number Query

The constellation of gps consists of 2/kloc-0 satellites and three backup satellites.

The GPS constellation consists of 24 satellites, of which 2 1 are working satellites and the other 3 are backup satellites.

GPS constellation is a satellite network, which runs in Earth orbit and provides global positioning service by sending and receiving radio signals. These 2/kloc-0 working satellites are distributed in six orbital planes, and each orbital plane has three satellites. These satellites orbit the earth once every 1 1.5 hours. They transmit time and location information by sending radio signals.

Ground user equipment can calculate its position by receiving these signals and measuring their arrival time. These 2/kloc-0 working satellites are enough to provide global navigation services. But in order to improve the reliability and stability of the system, there are three backup satellites in the GPS constellation.

Under normal circumstances, these backup satellites will not be started, but if any working satellite is found to be faulty or its performance is degraded, the backup satellite will be started to replace the faulty working satellite. These 24 satellites form a GPS constellation, which runs in Earth orbit and constantly sends and receives radio signals. The ground user equipment can calculate its position by receiving these signals and calculating their arrival time difference.

This design of GPS constellation can ensure that at least four satellites can be observed at any time and any place, thus providing accurate positioning information. In addition to providing location information, GPS constellation can also be used in many other applications, such as measuring time, speed and earth rotation. These applications are widely used in military, civil and commercial fields, which bring great convenience to people's life and economic development.
