G126 US93

None Aero-Radionav. VOR operates in the 108-117.975 MHz band and it shares the 108-111.975 MHz portion of the band with ILS localizers. The FAA operates 1,012 VOR, VOR/DME, and VORTACs including 150 VOR-only stations. This number of stations is expected to remain stable until the VOR/DMEs begin to be decommissioned in 2008. The band 112-117.975 MHz is also being utilized to transmit differential GPS (DGPS) correction to aircraft using Special Category-1 (SCAT-1) stations. The military also operates stations in the U.S. and overseas which are available to all users. As the U.S. transitions to satellite-based radionavigation, both VORs and ILSs are planned for partial or full decommissioning. Future aeronautical applications for this band include (1) expanded DGPS transmissions (SCAT-1 and/or LAAS), and (2) possible use as an expansion band for VHF A/G comm (117.975-137 MHz). VOR/DMEs begin to be decommissioned in 2008. Cat I ILS systems scheduled to be phased-down in 2008 while ILS Cat II and III will be needed beyond 2015. (See 1999 FRP).

RADIONAVIGATION

US224 S5.328

None Aero-Radionav. This band is heavily used for safety-of-life services within the national and international airspace systems. Nearly all aspects of aircraft identification, tracking, control, navigation, collision avoidance, and landing guidance are carried out. Major aeronautical radionavigation systems in this band include the Distance Measuring Equipment (DME), Air Traffic Control Beacons (ATCRBS), Mode-S, the military's tactical air navigation system (TACAN) and IFFSIF systems, and the Collision Avoidance System (TCAS). These aeronautical systems are not only essential to civil and military aircraft, but also to special users such as the U.S. Space Shuttle Program. Used throughout the world under International Civil Aviation Organization agreements.

Under US224, the Government is allowed to use this band for communications, navigation, and identification services on the condition that interference will not be caused to Aeronautical Radionavigation Services. These systems will be handled on a case-by-case basis. The military services use the Joint Tactical Information Distribution System (JTIDS) per US224.

Frequency 1176.45 MHz 12 MHz is planned for the new civil GPS signal (L5). As the U.S. moves to satellite-based aeronautical radionavigation, land-based DME/TACAN will be reduced to a minimum operational or backbone network. Target phase-down start date is 2008. Sea-based TACAN will be required in the foreseeable future. (See 1999 FRP). The FAA has also targeted this band for future navigation, surveillance and data communications systems for ATC. A sub-band centered on 981 MHz is currently being utilized for initial trials of the Universal Access Transceiver (UAT).
