Suppression. Electronic noise suppression and elimination of
interference shall be provided as set forth in the BESEP.
8.9  Satellite Communication Ground Stations.  A Satellite Communication
(SATCOM) ground station transmits and receives Radio Frequency (RF) signals to
and from a satellite in a fixed geosynchronous orbit.  This system provides
communications for large areas of the world using only one satellite. A
typical SATCOM ground station contains one or more large, rotating, dish-type
antennas equipped with a sensitive RF receiver and transmitter.  The site
usually contains buildings and/or transportables to house the RF equipment.
For further information, refer to NAVELEX 0101,105, Satellite Communication
System. Figure 14 shows the functional layout of a typical ground station.
Architectural and Structural
Configuration. The operations building shall contain an equipment
maintenance area. The building shall also house emergency generating
equipment and power conditioning equipment.  Pad and building layout will be
indicated by the BESEP.
Antenna Pad. The pad adjacent to the building shall be reinforced
concrete and shall provide for radome installation when required.  Hardstands
will also be required when transportable equipment is provided.
Floors. Raised flooring shall be provided for the fixed plant.
Flooring systems shall consist of 1-1/2 inch (38.1 mm) stringer widths, and
panels shall be 24 inches (0.61 m) square.
Mechanical.  Much of the electronic equipment associated with
satellite communications is provided by the satellite agency.  It may differ
from the electronic equipment in other Naval facilities, in that it normally
requires direct duct connections to the air conditioning equipment instead of
using room air for cooling.  Consult the BESEP for guidance.
Other requirements of Section 4 shall apply to the mechanical
design for satellite communication equipment.
Power Requirements. Primary and secondary power sources may be
either base-generated or commercial, but they shall be separate, reliable
sources. Emergency power for use during primary and secondary power outages
shall be provided by means of an emergency generator.  No-break power shall be
provided as set forth in the BESEP.  Lighting. Fluorescent lighting with approved RF filters may be
used in all areas, except inside the radome and in the immediate vicinity of
the  antenna.
