How many satellites are part of the GPS system?

The Global Positioning System (GPS) is designed to rely on a constellation of satellites that enables accurate positioning, navigation, and timing services. The minimum number of satellites required to provide continuous global coverage is 24, which is why this answer is correct.

The GPS network is structured around a minimum of 24 satellites arranged in six orbital planes, with each plane inclined at 55 degrees to the equator, ensuring that at least four satellites are visible from virtually any point on the Earth's surface at any time. This configuration allows for redundancy and ensures that even if a few satellites fail or are temporarily out of service, the system can still function effectively.

While there may be more than 24 satellites in the system—such as those added for redundancy and improved accuracy—the minimum operational requirement is indeed 24. This is essential for maintaining the integrity and reliability of the positional data provided to users globally.
