Download Free CLOSED CIRCUIT TELEVISION (CCTV) Description.pdf The closed circuit television (CCTV) system is used on orbit to provide support to orbiter and payload activities. This support includes transmitting real-time and recorded video from the orbiter to MCC through either the S-band FM or Ku-band communications systems. Mission requirements for CCTV and camera configurations are specified in the Flight Requirements Document for each shuttle flight.
The CCTV system consists of video processing equipment, TV cameras (and lens assemblies), pan/tilt units (PTUs), camcorders, video tape recorders (VTRs), color television monitors (CTVMs), and all the cabling and accessories required to make these components work together. All CCTV operations can be controlled by the crew. Most CCTV configuration commands can be executed by the Instrumentation and Communications Officer (INCO) at
Mission Control. Among the commands MCC cannot uplink are those to configure and operate loose CCTV equipment, such as camcorders and VTRs, and selection of inputs to the color monitors.
Standard CCTV components are powered via circuit breakers located on panel R14. Flightspecific keel cameras (prox ops or berthing) are usually powered from a cabin payload bus. CCTV pushbuttons on panel A7U have lights that illuminate to provide visual feedback on camera and CCTV routing configuration. These lights are powered via the ANNUNCIATOR light switches located on panel A6U.
