PART A - OPERATION AND FUNCTIONAL OVERVIEW OF THE G/VLLD
The G/VLLD set provides accurate target location data to support
conventional ordnance delivery, and designates targets for laser-seeking
The G/VLLD locates target coordinates by measuring distance,
elevation, and azimuth to aim-point with respect to the G/VLLD for remote
non-laser-seeking ordnance; and designates stationary/moving targets for
The G/VLLD set operates in the ground mode using a tripod mount; or in the
vehicular mode mounted on the M113A1 personnel carrier.
illustrates the G/VLLD set in the tripod mounted configuration. Figure 1-3
illustrates the G/VLLD mounted on the M113A1 personnel carrier.
The G/VLLD separates into four replaceable
assemblies. The four major units are:
Laser designator/rangefinder (LD/R).
Traversing unit (TU).
The two minor assemblies are:
LD/R backpack with lens cleaning kit.
Tripod/TU backpack with spare battery.
The following paragraphs describe the major units and assemblies of the
a. Laser Designator/Rangefinder (see figure 1-4A).
The LD/R contains
the electronics and controls for the system. It has a field of view of 3-4
degrees and a visual magnification power of 13X. The ranging capabilities
of the G/VLLD are classified. The LD/R mounts on the traversing unit.
b. Traversing Unit (see figure 1-4B).
The TU provides interface
between the LD/R and the tripod for ground mode operation, or with the
vehicle adapter assembly for vehicle mode operations.
It provides the
azimuth and elevation rotation for the LD/R and generates the azimuth and
elevation electrical data to the LD/R.
The TU measures the azimuth and
elevation with the following degrees of movement:
360€ (0 to 6399 MILS)
LOS - up 25€ (0 to 444 MILS)
- down 22.5€ (0 to -400 MILS)
