satellite constellation

A satellite constellation is a group of satellites working together in a specific arrangement to provide continuous coverage of the Earth's surface. Instead of relying on a single satellite, constellations ensure that signals for communication, navigation, or Earth observation can be received from multiple satellites at all times. This setup enhances reliability and reduces gaps in service. For example, GPS uses a constellation of satellites to pinpoint locations anywhere on Earth, enabling navigation for vehicles and mobile devices. Overall, satellite constellations play a critical role in modern technology and global connectivity.
