CELT (Coherent Emitter Location Testbed System)

CELT (Coherent Emitter Location Testbed System)

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The CELT is part of the Communications High Accuracy Airborne Location System. It

consists of three Distance Measuring Equipment (DME) Sets, three remote DMEs, and a

Ground Control DME. These subcomponents utilize High Speed Data Links (HSDL).

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

This system is able to produce potentially hazardous PDLs in excess of the safety

standard. Establish a Nonionizing Radiation Protection Program (IAW guidelines

provided in this TB) .

Hazard distance from antenna ....

Exclude personnel to a distance of 30 cm from the antenna. Instruct personnel to remain

in the fuselage when the hatch is open and the HSDL is radiating.

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

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

(CLD) Compact Laser Designator

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The CLD is a lightweight, man-portable, miniature target marker used

Type: Nd:YAG

by forward observers of target hand-off to laser-guided ordnance and

laser-tracker-equipped aircraft. The CLD also includes a rangefinder

capability.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Laser Classification..............

The CLD utilizes a Class 4 laser and requires an established laser safety program to

ensure its safe use. Develop a written Local Standing Operating Procedure (SOP) IAW

guidance provided in this TB.

Laser Hazard distance ..........

Do not permit personnel to view the beam at distances less than 9.7 m for unaided

viewing. Do not permit personnel to view the beam at distances less than 38 km for 5 cm

magnifying optics, 48 km for 8 cm magnifying optics, and 58 km for 12 cm magnifying

optics.

Ocular injury .....................

When viewing the CLD laser with the naked eye, use protective eyewear that filter at

1064 nm with a minimum O.D. of 4.5. When viewing the CLD laser with magnifying

optics, use protective eyewear that filter at 1064 nm with a minimum O.D. of 5.4.

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

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