TSM-Warfighter Information Network-Tactical

Joint Network Management System

The Joint Network Management System is being developed to provide commanders in chief and joint-forces commanders with a joint communications planning and management system. The request for proposal was released to industry Oct. 19, 2000. Proposals from prospective contractors were received Dec. 4, 2000. Source selection was scheduled to be final in April, followed by a contract award in May.

Army Key Management System

New-equipment training local communications-security-management software with Release 3 software is ongoing. To date, more than 220 Army accounts have been trained and fielded.

NET is scheduled to run through January 2002. Resident training at the Signal Center is scheduled to begin about March 2002. The Communications Security Logistics Agency at Fort Huachuca, Ariz., will provide interim training until the Signal Center’s resident course is stood up.

The transition to Phase 4 software will begin with the establishment of 100 pilot accounts. Follow-on procedures for Phase 4 transition will be under CSLA’s direction. LCMS adjunct-training facilities are being coordinated for U.S. Army Europe and Korea.

The system-assessment report from the automated communications-engineering software limited-user test – held July-August 2000 – was released March 1. The product manager for ACES seeks a conditional materiel release with fielding expected to begin this summer.

Data-transfer device study

One of the critical subsystems under the Army Key Management System program is the CYZ-10, commonly referred to as the data-transfer device. Training and Doctrine Command’s system manager for Warfighter Information Network-Tactical and the Signal Center’s combat-developments directorate are studying the DTD to validate existing quantities as well as look at distribution strategies for new versions of the device.

Integrated-systems control

The integrated-systems control provides an automated, theater-wide facility the Signal commander and staff will use to plan, monitor and manage multiple tactical-communications systems to support warfighters, weapon systems and battlefield automated systems. ISYSCON replaces the SCC-2 network-planning terminal and communications-system control element, and manages the Army’s transitioning wide-area networks.

ISYSCON provides a common network platform from theater through division: a (V)1 at TSC(A), Signal brigades and division Signal battalions, and a (V)2 at echelons-above-corps and corps battalions. (This configuration is a single shelter and standard integrated command-post system tent with two servers and two workstations). A laptop for EAC Signal companies is being planned.

The EAC planning and Army Battle Command System 7.0 compatibility capabilities are under development, with release planned for 2002. This release will improve situation awareness by providing a Signal common tactical picture. It also provides collaborative planning and execution.

The ISYSCON system achieved materiel release for Army-wide fielding March 15.

TSM-Tactical Radio

Enhanced Position Location Reporting System

An acquisition strategy was approved to procure 12,897 Enhanced Position Location Reporting System radio sets until the Joint Tactical Radio System is fielded in Fiscal Year 2004 or later. EPLRS planning and fielding for the initial brigade combat teams continues to be a priority for material developers and trainers, as well as retrofit of radio sets and deliveries of the full-rate production fielding radio sets.

As EPLRS evolves, many more enhancements such as higher capacity and restructured network-bandwidth allocations should permit improved service and allow increased data-rate implementation. These additional enhancements will be backward compatible and retrofitted into EPLRS’ earlier versions.

Development of the EPLRS network manager for elimination of the net-control stations continues. The objective fielding of this capability will be with 3d BCT.

All these improvements are designed to support data transmission in and through the tactical Internet.

Joint Tactical Information Distribution System

To date, production terminals have been fielded to Patriot units in Germany and to Fort Bliss, Texas, as well as to short-range air defense units in 82d Airborne Division, 101st Airborne Division, 2d Infantry Division, 3d Infantry Division, 4th Infantry Division, 10th Mountain Division, 1st Cavalry Division and the Alabama National Guard (Patriot). The theater high-altitude area-defense program has also received five terminals.

Multifunction Information Distribution System

The Multifunction Information Distribution System’s essential mission is to improve secure, jam-resistant information flow and interoperability among Army, Navy, Air Force and North Atlantic Treaty Organization elements as well as Army elements on the battlefield.

The Navy is the lead service for MIDS, and the Space and Naval Warfare Systems Command is the contracting activity. The Army’s management activity is the Army product manager for JTIDS/MIDS.

MIDS is being fielded to Patriot, THAAD and medium-extension air-defense-artillery platforms.

Near-term digital radio

The near-term digital radio was groomed as an interim radio to communicate among tactical-operations centers. NTDR has demonstrated enough technical maturity to meet data-transfer requirements between brigade TOCs at the Division XXI advanced warfighting experiment.

NTDR’s mission in this role was to provide data communications to the mobile TOCs for Army tactical command-and-control systems from battalions to brigade, and to serve as a back-up to asynchronous-transfer mode and high-speed multiplex networks at brigade and above. Bandwidth capability of up to 288 kilobytes per second was demonstrated over the 13-radio NTDR network during the DAWE.

Initial-production models used in an experiment at Fort Huachuca during 1st Quarter FY01 revealed there were still deficiencies in the radio that must be corrected before delivery to the first digitized division and the BCTs being formed at Fort Lewis, Wash. Deliveries to 4th Infantry Division’s Central Technical Support Facility and first IBCT began in 2d Quarter FY01.

Joint Tactical Radio System

The Joint Tactical Radio System will provide warfighters with fully digital radio communications, both horizontally and vertically, throughout the battlespace. Operators in the field will be able to expand and modify the capacity and capability of individual radios, links and networks to accommodate user demand.

This family of advanced, reliable and dynamic radios will be networked together. JTRS will be software-programmable to operate at the same time on multiple bands, in multiple modes and on multiple networks. JTRS will also allow simultaneous voice, data and video communications.

JTRS will operate with legacy equipment and waveforms used by military and civilian land, air, surface ship, man-mobile and vehicular platforms. The family of radios will be scaleable by virtue of form, fit and function to meet specific operational needs. JTRS will also provide growth capability through an open-system design that allows technology insertion through evolutionary or preplanned product improvements.

Ultimately, JTRS will provide a networked, multiband, multimode service with voice, video and data capabilities for all the Defense Department.

The TRADOC system manager for tactical radios’ office is supporting future communication needs for the Army’s interim and objective forces with JTRS. JTRS is the key program for this office. While enhancements to EPLRS and other tactical-radio systems are necessary to support the legacy force, it’s JTRS with its embedded routing and retransmission – as well as its capability to self-organize and maintain mobile networks in support of command-and-control on-the-move – that will enable the Army’s transformation from TOC-centric towards network-centric, and eventually to commander-centric, warfare.
