GPS is a radio navigation system of how many satellites operated by which organization?

• A. 32, NASA
• B. 24, DOD
• C. 28, NOAA
• D. 20, FAA

Answer: (B)

Global Positioning System works by using a fixed constellation of satellites to provide precise location information anywhere on Earth. The system is designed to have at least 24 satellites in orbit to ensure reliable, global coverage, and it is operated and maintained by the U.S. Department of Defense. While NASA, NOAA, and the FAA are important players in space, weather, and aviation, they do not own or operate the GPS constellation. The DOD manages the satellites, the ground control, and the signals that receivers use to determine position.
