PART A - IDENTIFICATION OF COMPONENTS
AND CONTROLS OF THE G/VLLD
The G/VLLD set provides accurate target location data to support
conventional ordnance delivery, and designates targets for laser-seeking
ordnance. 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; it designates stationary or moving targets
for laser-seeking ordnance.
The G/VLLD set operates in the ground mode using a tripod mount, or in
the vehicular mode mounted on a 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 is transportable. Two men afoot transport the system using
two backpack assemblies (if used, the night sight requires an additional
man), or it may be moved by vehicle. One man may operate the G/VLLD from
either a kneeling or sitting position.
The G/VLLD operates on a self-contained rechargeable battery or from a
vehicle source using a 25-foot vehicle cable with a filter. When mounted
on the support tripod, it accommodates terrain with up to 20-degree
slopes. The azimuth locator coordinate adjusts to any reference value.
The G/VLLD separates into four replaceable major units and two minor
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 is the
heart of the G/VLLD, containing 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
