Ground Control Network

A Ground Control Network (GCN) is a system of communication and management stations that monitor, coordinate, and control satellite operations from the Earth's surface. It consists of interconnected ground stations equipped with antennas and computers that send commands to satellites and receive data from them. GCNs ensure satellites function correctly, execute planned maneuvers, and gather telemetry for health and status reports. They are essential for satellite navigation, communication, weather observation, and space exploration, providing the vital link between space assets and mission control teams on the ground to maintain safe and effective operations.
