Joint Combat Information Terminal (JCIT) Specifications

A Solution To The Joint Tactical Radio Requirements Today

8 Multi-Band Transceiver Channels, 2.0 To 512.0 MHz, Expandable Beyond 2.5 GHz
Embedded COMSEC/INFOSEC, 14 Algorithms, Electronic Key Management System
Software Reconfigurable to Enable Mix of Voice, Video and Data on Demand
Enables Interoperability Among Service, International and Coalition Partners
MIL-STD-810 Test Levels Support Land Based, Airborne, Surface and Sub Surface Employment

JCIT uses advanced digital and RF technology to provide unprecedented battlefield connectivity and combat information processing in a compact, modular, on-the-fly, reconfigurable, open system architecture. Up to eight multiband transceivers, twelve INFOSEC channels, fifty-five processors, and GPS as well as the requisite key management, mass storage, and power supplies are housed in a 3/4 ATR or 19" rack mounted chassis weighing less than 50 lbs.

It is capable of simultaneously transmitting, receiving, encrypting, decrypting, and processing data, voice, and video from all current and planned military data links, broadcasts, and voice channels. The system is software reprogrammable to support a variety of mission scenarios. The design enables interoperability with legacy systems as well as with inter-service, inter-national, and coalition partners. Using a SEM-E packaging scheme, JCIT has twenty-five module spaces available. Employing twenty of these in its current design, five are available to integrate additional capabilities like navigation, IFF and GBS into the baseline configuration. The architecture allows additional flexibility by varying the mix of channels to tailor the system to platform specific needs. Achieving much of its functionality and diversity in software, it is designed to host evolving and expanding C4I needs. The system provides multiple user interfaces via a variety of voice, video, and data ports.

JCIT has been developed by the Naval Research Laboratory (NRL) to support U.S. Army Aviation Airborne Command and Control requirements. It employs an open system hardware and software architecture that is government owned and therefore non-proprietary. Significant design emphasis has been placed on ensuring its ability to support horizontal technology insertion. This has produced an extremely flexible, expandable and cost effective means of achieving enhanced platform capability while requiring less power, at less weight, in a smaller volume and at a lower cost. Having been designed for airborne (including aircraft carrier) use, it is fully qualified for land, naval surface and sub-surface applications. JCIT hardware and software is currently available for demonstration and evaluation.
