Joint Tactical Terminal (JTT)

Primary Purpose JTT is a special application UHF (225-400 MHz)

tactical intelligence terminal which provides the

capability to disseminate time sensitive

Command, Control, Communications, Computer, and

Intelligence (C4I), and battlefield targeting

information to tactical commanders and

intelligence nodes. The JTT receives signals

from the Integrated Broadcast System which

integrates multiple intelligence broadcasts into

a system of systems, and migrates tactical

receive terminals into a single, related Joint

Tactical Terminal (JTT) family. The goal of the

Integrated Broadcast Service (IBS) is to resolve

the uncoordinated proliferation of "stovepipe"

intelligence/ information broadcasts by providing

the tactical commander with integrated

time-sensitive tactical information.

Sub-Functions The terminals allow Army, Air Force, Navy and

Marine Corps users to exploit Integrated

Broadcast Service (IBS) networks: Tactical

Reconnaissance Intelligence eXchange Service

(TRIXS), Tactical Information Broadcast Service

(TIBS), Tactical Related Applications (TRAP), and

Tactical Data Information eXchange System-B

(TADIXS-B). In addition to receiving intelligence

data, JTT and CTT transmit TRIXS or TIBS data.

The CTT and other IBS terminals are migrating to

a single JTT family.

Equipment Requirements The baseline JTT is not a stand-alone system, but

consists of two line replaceable units (LRU)

(the Receiver Exciter (RE) and the Power

Amplifier (PA)) provided by the Program Manager

as Government furnished equipment (GFE) and which

must be integrated into a C3I host provided by

the user. The user is required to provide all

antennas, pre-amplifiers, cables, TDP/workstation

and other associated equipment. The JTT baseline

(JTT T/R) consists of both an RE and PA, and

provides the ability to receive on up to eight

channels and transmit on one channel

simultaneously. Additional PAs could be added

(max of 4) to provide additional channels up to

the maximum of 12 receive and 4 transmit. The JTT

Receive Only Terminal (JTT R) is capable of

receiving eight channels simultaneously and

contains the RE only. Additional configurations

and being considered to include a stand-alone

suitcase-size terminal for Army Special Forces

(JTT B) and a reduced size JTT for use on

airborne platforms (JTT A). These and other

configurations would be part of the JTT family of

terminals, but they are not currently in


Connectivity Requirements LAN: 10/100 MHz Ethernet, RS-232/422,

MIL-STD-188-114, MIL-STD-1553. Also uses GBS,

EHF SATCOM, SIPRNET, JWICS, etc and other netted


Crypto Requirements Uses whatever cryptographic means the radio

transmission system or network is running up to


Normal Locations The JTT is integrated into other weapon systems

and are transported with the host system. The

equipment can be mounted in fixed and rotary wing

aircraft, surface, and fixed or mobile ground

platforms and vehicles.

Information Managed Targeting, tracking, global detection and cueing

depending on what system it is receiving

information from over the IBS.

Products Created Depends on what information is being received

over the IBS. Graphics to intelligence contact
