A microwave scanning beam landing system from the 1950s and 1960s is still operating routinely. It depends on airborne reception of pulse-coded signals from mechanically scanned antennas. Military versions include the US Navy's C-Scan for carrier landings and the Tactical Instrument Landing System used in Sweden. Other sets, called microwave scanning beam landing systems, serve Space Shuttle orbiters. System concepts and functional hardware requirements were tested extensively by on-ground and flight procedures. Both the US Navy and Sweden purchased operational equipments in 1969.<>
