Nearly all satellite missions - commercial, military or scientific - use Ground Systems to control and manage their operations. Ground Systems operate 24 hours a day, 7 days a week, 365 days a year and can often support multiple spacecraft. These Systems consist primarily of a large antenna that communicates with the orbiting spacecraft via radio waves, called a telecommunications link. Ground Systems are responsible both for transmitting information (such as command and control instructions for orbital corrections) and receiving information (such as telemetry data about where the satellite is located).
