PURPOSE

GPS CONCEPT

24 SATELLITES IN 6 ORBITS, 6-9 ARE IN VIEW OF THE GPS RECEIVER AT ANY TIME

REQUIRES A MINIMUM OF 3 SATELLITES FOR LOCATION AND 4 FOR ELEVATION

UTILIZES PRECISE TIMING FROM SATELLITE TO RECEIVER TO DETERMINE LOCATION AND ELEVATION

REQUIRES LINE OF SIGHT TO SATELLITE RCVR

COMSEC ALLOWS MAXIMUM ACCURACY

GLOBAL POSITIONING SYSTEM

PHYSICAL FEATURES

PLGR
CHARACTERISTICS

ALL WEATHER OPERATION

NO SIGNALS EMITTED TO REVEAL YOUR POSITION

HOLDS 52 DATUMS

IS COMPATIBLE WITH NIGHT VISION DEVICES

RESISTS JAMMING (SPOOFING)

WATER-PROOF TO ONE METER

RUNS ON INTERNAL BATTERIES OR EXTERNAL POWER SOURCE

LITHIUM OR AA BATTERY ADAPTER

ADAPTER FOR 12 VDC OR 120 VAC

PLGR OPERATION OBJECTIVES

SETUP THE PLGR TO RECEIVE SATELLITE DATA.

DETERMINE YOUR PRESENT POSITION

INITIALIZE THE PLGR

ENTER WAYPOINTS

NAVIGATE TO A WAYPOINT

PLGR Cold Start or Standby

Cold Start:

If PLGR has not been used for a month or more or if the Almanac is old

Present position greater than one degree from last known position

Standby:

PLGR has been used within a few days AND present position within one degree of last known position

PLGR Cold Start

Physical check

Self-test check

Power battery check

Verify crypto loaded

Crypto loaded: SV equals all-Y

Crypto not loaded: SV equals mixed

Set operation mode to Continuous

Initialize position

Monitor FOM (=1) and almanac age (1 day)

Load waypoints

PLGR Standby

Physical check

Power battery check

Set operation mode to Continuous and SV type to mixed

Monitor FOM (=1) and almanac age (1 day) and load waypoints

TURNING ON THE PLGR

PHYSICAL CHECK

Inspect PLGR for:

Dents, scratches, punctures

Unreadable data plates

Keys for cracks, breaks, unreadable markings

Display window for cracks or cloudy

Missing or loose hardware

antenna

covers

connectors

SELF-TEST CHECK

Upon power up - self-test status will be displayed

Or

POWER BATTERY CHECK

Tan PLGR - 10 hrs, Green PLGR - 20 hrs

Upon power up - battery status will be displayed

Or

PLGR BATTERIES

Memory Battery - not a AA battery, but AA size, replace yearly when loading new crypto

Power Battery - disposable

Tan case - 10 hours

Green case - 20 hours

MAP DATUM

MAP DATUM

A datum is a surveyed line or point that ensures all maps within a series will correctly match when placed edge to edge.

Fifty-two map Datum sets are available within the PLGR.

SETUP I/O

AUTOMARK

PLGR CRYPTO

NSA certified that the PLGR is considered unclassified when keyed.

Loaded yearly or as required

Can be loaded with KYK-13, KOI-18, CYZ-10

Key material gives the PLGR greater accuracy in positioning by accessing secure satellites too
