GUARDRAIL/Common Sensor Ground Station (GRCS)

GUARDRAIL/Common Sensor Ground Station (GRCS)

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The GRCS consists of three Interoperable Data Links (IDL), a

CLASSIFIED (IDL)

Low Band Antenna (LBA) Field, an Integrated Processing

5.925 6.425 GHz (C Band) (FST-2000)

Facility (IPF), a Remote Relay System (RRS)/the FST-2000,

7.9 8.4 GHz (X Band) (FST-2000)

and a support building to house the GRCS. The FST-2000

14 .0 14.5 GHz (Ku Band) (FST-2000)

Terminal utilizes a cassegrain-fed, log periodic reflector

antennas with diameters of 4.5 m for transportability and 11 m

Power:

70 W max (IDL)

for fixed-station usage. The LBA and IPF utilize a Low-Band

400 W PEP (C Band) (FST-2000)

Horizontal Dipole antenna, a Low-Band Vertical

350 W PEP (X Band) (FST-2000)

Monopole/Monocone antenna, Mid and High-Band antenna

300 W PEP (Ku Band) (FST-2000)

masts, and ARF antennas mounted on the aircraft.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

This system is not able to produce potentially hazardous PDLs in excess of the safety

standard and is not subject to radiation protection control.

Open/cracked waveguides.......

The area between the IDL and FST-2000 antenna feed horn and reflector and any open

waveguides produce potentially hazardous PDLs within short ranges (2.0 2.5 m for the

FST-2000). Instruct personnel to avoid these areas. Inspect FST-2000 semi-rigid

waveguides periodically for breaks or cracks, and replace any suspect waveguide.

RF shock/burn ......................

Observe standard RF shock precautions. Do not touch any LBA antennas when

energized.

Other.................................

Consult the equipment Technical Manual for other operator and/or maintenance hazards.
