2022年6月28日 · The GPS space segment consists of a constellation of satellites transmitting radio signals to users. The United States is committed to maintaining the availability of at least 24 operational GPS satellites, 95% of the time. To ensure this commitment, the U.S. Space Force has been flying 31 operational GPS satellites for well over a decade.

2023年9月25日 · Today the GPS satellite constellation (the space segment) consists of over 30 operational satellites, each equipped with redundant atomic clocks and tracked by a ground control network (the control segment). Each satellite transmits its position and time at regular intervals and those signals are intercepted by GPS receivers (the user segment).
Chapter 3: GPS System Segments | GlobalSpec
GPS is comprised of three segments: satellite constellation, ground-control/monitoring network, and user receiving equipment. Formal GPS JPO programmatic terms for these components are space, control, and user equipment segments, respectively. The satellite constellation is the set of satellites in orbit that provide the ranging signals and ...
Global Positioning System (GPS) Overview | Navigation Center
GPS consists of three segments: space, control, and user. The Space Segment consists of a minimum of 24 operational satellites in six circular orbits 20,200 km (10,900 NM) above the earth at an inclination angle of 55 degrees with an 11 hour 58 minute period.

Together, the satellites, control centers, and users make up the three segments on which GPS relies: the space segment, the control segment, and the user segment. These segments communicate using radio signals.
The GNSS consist of three main satellite technologies: GPS, Glonass and Galileo. Each of them consists mainly of three segments: (a) space segment, (b) control segment and (c) user segment. These segments are almost similar in the three satellite technologies, which are all together make up the GNSS.
