Q. What is Joint Surveillance System:(JSS)?
A. JSS is a joint USAF/FAA radar network.providing communication and radar data to both FAA and USAF control centers.. JSS has been activated in 1983 replacing the former Semi Automatic Ground Environment (SAGE) system.
Q How is it working?
A. The FAA equipment is a mixture of Air Route Surveillance Radar (ARSR) 1, 2, and 3 systems. The USAF equipment are Air Route Surveillance Radar Model 4 (ARSR-4).radars providing air defense and air traffic control for the continental United States, Guam, and Hawaii. These are epuipped with UHF ground-air-ground (G/A/G) transmitter/receiver (GATR) facilities and several sites have VHF radios as well. The GATR facility provides radio access to fighters and Airborne early warning and control (AEW&C) aircraft from the Sector Operations Control Centers (SOCC).
Q. What is a Sector Operations Control Center?
A. A SOCC is responsible for collecting and analyzing all radar data in its sector. Based on its data it commands and controls the airdefence assets in its sector which may be deployed to counter threats.
JSS radars transmit data to the SOCCs who then forward tracks of interest to the CONUS ROCC and NORAD. Radar and track data are sent through landlines as TADIL-B data and through HF links as TADIL-A data. Both links are provided by the Radar Data Information Link (RADIL). CONUS SOCCs communicate with the CONUS ROCC and NORAD by voice and data landline circuits.
