A satellite constellation is a group of satellites that work together to provide coverage over a specific area of the Earth. These satellites are usually placed in similar orbits, allowing them to communicate with each other and share data. This arrangement helps improve the accuracy and reliability of services like global positioning systems (GPS) and telecommunications. Many modern satellite constellations are designed to provide global internet coverage, especially in remote areas. Companies like SpaceX with its Starlink project aim to deploy thousands of small satellites to create a network that can deliver high-speed internet to users around the world.
