Space Force Satellite Control Network Is In Urgent Need of Upgrades, Watchdog Says
April 11, 2023 | By David Roza
The Space Force system for controlling U.S. government satellites is in urgent need of an update, and the branch also needs an up-to-date plan for delivering it, the Government Accountability Office said in a report published April 10.
The Satellite Control Network (SCN) is made up of 19 antennas stationed around the world, from Diego Garcia Island in the Indian Ocean to the village of Oakhanger in southern England to Schriever Space Force Base, Colo., where the primary control center for SCN is located.
SCN operators use the antennas to track a satellite’s location, collect its health and status reports, and send signals to control its subsystems such as power supply, antennas and mechanical and thermal control. These functions are collectively called tracking, telemetry, and commanding (TT&C), and satellite users across the federal government rely on the Space Force’s SCN operators for TT&C support.
The satellites controlled by the SCN support a wide range of important activities such as positioning, navigation, and timing; intelligence, surveillance and reconnaissance; missile warning and missile defense; communications; weather; and research and development, the GAO noted in its report. But as space becomes increasingly crowded with government satellites, the growing demand for SCN operations has fallen on an aging antenna network that is difficult to maintain and too small to meet the need.
