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.

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).

Surveillance Radars. This band is jointly used by
the FAA and DOD for radiolocation performing long-range air surveillance and safety-of-flight enroute air
traffic control under Joint Surveillance System
agreements. The military services make use of the
band for high-power long-range surveillance radars on
land and ships in support of national defense
missions. The DOD and FAA recently deployed a
modernized Air-Route Surveillance Radar Model 4
(ARSR-4) in this band for air-defense, drug
interdiction and air-traffic control.
GPS. The frequency 1227.6 MHz � 12 MHz is
designated for the Global Positioning System (GPS)
as part of the radionavigation satellite service. This is
a 24- satellite constellation system with large
numbers of U.S. and international users.
Drug Interdiction. In this application, radar
equipment is mounted on tethered balloons along the
southern border of the U.S. to detect low-flying aircraft
entering U.S. airspace.
NASA. Space research and Earth exploration-satellite activities for active microwave sensor
measurements of geological surfaces and ocean
wave structure are performed by NASA. |
