960-1,164 MHz
AERONAUTICAL
RADIONAVIGATION

Used worldwide for electronic aids to air navi-
gation, including distance measuring equipment
(DME), tactical air navigation (TACAN), sec-
ondary surveillance radars (SSR), and ADS.
Some nations permit Link 16 (a military com-
munication system) usage on a noninterference
basis.
GPS L5 and GALILEO E5A are at 1,176.45
MHz, GALILEO E5B is at 1,207.14 MHz. A
number of other radionavigation-satellite sig-
nals are planned for the 1,164-1,215-MHz
band.

AERONAUTICAL
RADIONAVIGATION

Used worldwide for primary radars for purposes
including air traffic control, military surveillance,
and drug interdiction. Thirty-one countries have
coprimary allocations for fixed and mobile ser-
vices. Band also used for active spaceborne sen-
sors (e.g., for ocean surface measurements).
GPS L2 is at 1,227.6 MHz.
GLONASS L2 and GALILEO E6 frequencies are
within the 1,240-1,300-MHz band.
