A satellite constellation is a group of satellites working together in a coordinated manner to achieve a specific objective, such as providing global coverage, communication services, monitoring the Earth's surface, or conducting scientific research. These satellites are typically placed in various orbits around the Earth to ensure continuous coverage and optimal performance. Satellite constellations are often used in telecommunications, remote sensing, navigation, and weather forecasting applications. They offer advantages such as redundancy, increased coverage, and improved data collection and processing capabilities compared to single satellites.
