GEO satellite constellations

GEO satellite constellations are groups of communication satellites positioned in geostationary orbit, approximately 35,786 km above Earth, where they appear stationary relative to the surface. These satellites work together to provide global coverage, enabling services like internet, TV, and GPS. Unlike a single satellite, a constellation offers redundancy and wider coverage, as multiple satellites coordinate to ensure consistent service even if one fails. Their strategic placement helps deliver reliable, continuous communication across large areas, making them vital for global connectivity and various satellite-based applications.
