AN/PRC-112G ® CSAR Transceiver

Fielded. Proven.Trusted.

GPS capabilities into a sin-

gle handheld radio for military,

paramilitary, law enforcement, and government agencies.

And it communicates to our plug-and-play Quickdraw2 ®

Interrogator onboard a wide variety of fixed- or rotary-wing

aircraft or on a U2 or UAV. The radio is also interrogatable

by the RSC-125G 2 or AN/ARS-6 Version 12 PLS ® 3 , as an

independent location method, using DME.

Blue Force Tracking Capability

The versatile AN/PRC-112G radio can store up to 250

navigational waypoints, enabling it to be used as a stand-alone

GPS receiver for navigation and route management — or as a

VHF/UHF AM transceiver for ground-to-air communications.

In addition, several of our future upgrades are aimed at

enhancing its ability to be used to locate assets and personnel

for Blue Force Tracking. We plan to include full imple-

mentation of an LPE waveform as an option to the

AN/PRC-112G radio, if approved by the Government. Its

TDMA structure and AM/FM modulation will allow it to

securely support communications among thousands of users

simultaneously. And we delivered L-band handheld units

for the PRESS ACTD in 2004 using Global Personnel

Recovery System technology. Once GPRS technology is

minaturized, we plan to integrate it into our radio, combining

BFT, CSAR and Situational Awareness capabilities in a

single unit.

Continually Updates and Detects GPS Interference

The radio contains a CA code, 12-channel parallel GPS

Receiver, with position updates each second. And it

detects GPS interference, providing visual notification of

its presence and relative strength. Interoperable with over

31,000 PRC-112 and HOOK2 family radios delivered to

U.S. and international customers, the AN/PRC-112G radio

is perfect for unilateral or coalition operations. Best of all,

the radios are continuing to save lives around the world.

Twenty-five years. Over 17,000 HOOK2 ® radios sold.

Countless lives protected and saved. That’s history! Two-

way SATCOM and 406 SARSAT via software upgrade.

Terminal area communications. Coalition and HOOK

family interoperability. Enhanced BFT capability. That’s

today! DAMA-C SATCOM. Automatic activation. L-Band

GPRS. Roadmap to SCA/JTRS. That’s tomorrow. That’s

the AN/PRC-112G ® radio!

Software Defined. Upgradeable. Interoperable.

The latest in the line of HOOK2 ® CSAR products, the flexi-

ble, easy-to-use AN/PRC-112G transceiver is fully upgrade-

able so you can add new features and waveforms as they

become available. In fact, 2-way SATCOM and 406 SARSAT

beacon modes are available now as software options 1 , and

additional capabilities are planned. This spiral develop-

ment approach also allows you to field this proven technology

right now. And the radio is based on — and backwards com-

patible with — the field-proven AN/PRC-112, AN/PRC-

112B (HOOK-112) and AN/PRC-112B1 radios.

LPI/LPD Communications in Just 1 Button Press

The upgraded AN/PRC-112G radio sends encrypted global

positioning (lat/long or GEO), message and identification,

providing essential, quick and accurate location and rescue

information for air crews, forward air controllers and personnel

operating in hazardous conditions. And the single, short

encrypted burst to CSAR aircraft provides low probability

of detection and interception communications.

Multiple Terminal Area Communications and

Guidance Modes

The General Dynamics AN/PRC-112G radio features direct ,

line-of-sight voice and encrypted two-way data communica-

tions between the survivor and the rescue forces — with no

handoffs required. It also combines Distance Measuring

Equipment (DME), beacon, transceiver, transponder and

The GPS-112 Program Loader – Improved

The GPS-112 Program Loader consists

of an interface box, a cable set and a

Windows ® -based software package to

enable the user to easily and quickly

load encryption key, datum, frequencies

and user I.D. codes into the AN/PRC-

112B (Hook 112), AN/PRC-112B1

and AN/PRC-112G transceivers and

the Quickdraw and Quickdraw2

Interrogators. It also now includes a

set-up wizard and a cloning feature. It

can also load new Operating System

software as upgrades become avail-

able as well as program the legacy

AN/PRC-112 radios.

1 To add the 406 SARSAT option, all radios must be

returned to the factory for upgrade, due to COSPAS/

SARSAT regulations. For radios with NSN#5820-

01-526-8808, the 2-way SATCOM option is a field-

installable software upgrade. Radios with NSN#

5820-01-504-5465 must be returned to the factory

for a hardware upgrade to add either option. Call for

a quotation.
