Fleet Satellite Communications System and Subsystems |
FLTSATCOM system and is used in particular to
support the Navy Fleet Broadcast system. The
AN/FSC-79 operates in the 7- to 8-GHz band and is
designed
for
single-channel
operation.
The
AN/FSC-79 terminal is installed at the four
COMMAREA
master
stations
and
NAVCOMTELSTA Stockton, Calif.
The AN/WSC-3 Transceiver is the standard
UHF SATCOM transceiver for both submarine and
surface ships. The AN/WSC-3 is capable of
operating in either the satellite or line-of-sight
(LOS) mode and can be controlled locally or
remotely.
The unit is designed for single-channel, half-
duplex operations in the 224- to 400-MHZ UHF
band. It operates in 25-kHz increments, and has 20
preset channels. In the SATCOM mode, the
AN/WSC-3 transmits (uplinks) in the 292.2- to
311.6-MHz bandwidth and receives (downlinks) in
the 248.5- to 270.1-MHz band. A separate transceiver
is required for each baseband or channel use.
The AN/WSC-5 UHF Transceiver (figure 2-10) is
the common UHF RF satellite terminal installed at
NAVCOMTELSTAs for the GAPFILLER subsystem.
In FLTSATCOM operations, it is used as the common
RF terminal for all subsystems except the Fleet
Satellite Broadcast (FSB) and the Antisubmarine
Warfare information Exchange Subsystem (ASWIXS).
The AN/WSC-5 can be used to back up the AN/FSC-
79. The AN/WSC-5 transmits in the 248.5- to 312-
MHz range and receives in the 248.5- to 270.1-MHz
range.
The AN/ARC-143 UHF Transceiver (figure 2-11)
is used for ASWIXS communications and is installed
at VP Antisubmarine Warfare Operation Centers and
aboard P-3C aircraft. The unit two parts: a transceiver
and
a
radio
set
control.
