A satellite constellation is a group of artificial satellites working together in coordinated orbits to provide continuous and wide-area coverage for services such as navigation, communication, or Earth observation. Unlike a single satellite, constellations are strategically positioned so that at least one satellite is always in view from any point on Earth, ensuring seamless connectivity and data transmission. This approach is essential for global systems like GPS, satellite internet, and weather monitoring, as it overcomes the limitations of individual satellites and enhances reliability, speed, and coverage.
