Space Squadron was responsible for flying a constellation of Skynet satellites, up to the fourth iteration of six space vehicles which supported Army, Royal Navy and Royal Air Force units. The space vehicles were controlled on a permanent basis from Oakhanger, with command and control traffic being passed from one of the three ground stations. Space Squadron also controlled the flight of space vehicles on behalf of NATO, with an earth station at the nearby NATO ground terminal. The constellation comprised geosynchronous satellites, providing Earth coverage and higher-power coverage over Northern Europe.
