The new Space Fence was envisioned to be a system of two or three S-band ground-based radars designed to perform uncued detection, tracking and accurate measurement of orbiting space objects, and was intended to replace the Air Force Space Surveillance System, or VHF Fence, that was transferred from the US Navy to the US Air Force in 2004.
The new Space Fence was planned to be a system of two or three S-band ground-based radars intended for unguided detection, tracking, and precise measurement of orbiting space objects. It was designed to replace the Air Force Space Surveillance System, formerly known as VHF Fence, which was transferred from the US Navy to the US Air Force in 2004.
