The Space Defense Center (SDC) was a space operation center of the North American Aerospace Defense Command. It was successively housed at two Colorado locations, Ent Air Force Base, followed by Cheyenne Mountain's Group III Space Defense Center[1] The 1st Aerospace Control Squadron manned the SDC at both locations, which used the Electronic Systems Division's 496L System for processing and displaying data combined from the U.S. "Air Force's Space Track and the Navy's Spasur" (NAVSPASUR).[2][3]
