ABSTRACT (maximum 200 words) To meet the increasing need for additional wideband satellite capability within the Department of Defense, the Global Broadcast Service (GBS) is being developed. GBS is an asymmetric network providing up to 24 Mbps from the Satellite Broadcast Manager (SBM) to deployed forces via UHF Follow On (UFO) satellites during GBS Phase Two. The concept of Smart Push provides for most of the users' needs but cannot anticipate every need or emerging needs of the user. The user through User Pull requires the ability to request information products from the SBM through existing communication paths. This capability is termed reach back. Due to the nature of operations, not as much information is sent back from operating forces to headquarters commands; therefore, less bandwidth is required from deployed forces to headquarters. commands. Reach back channels do not require as much bandwidth as GBS. This research explores the viability of using Satellite Tactical Digital Link J (S-TADIL J), also known as Satellite Link 16, as a reach back option for GBS. 14. SUBJECT TERMS 15.

    NEWS RELEASE FOR IMMEDIATE RELEASE Contact: John Wranovics M: 925.640.6402 [email protected] Curtiss-Wright Intelligent Tactical Data Link Translation Gateway Improves and Simplifies Real-time Warfighter Communications New HUNTR™ software application lets JTACs and TACPs easily create a Multi-Tactical Datalink Network that supports Link 16, VMF, Cursor-On-Target (CoT), JREAP, SADL, and CESMO data exchanges between ground forces, aircraft, ships, and C2 elements ASHBURN, Va. – September 9, 2019 – Curtiss-Wright’s Defense Solutions division, a trusted leading supplier of Tactical Data Link (TDL) software and hardware solutions, announced today that its Tactical Communications Group (TCG) business has introduced HUNTR (TDL Hub and Network Translator), a new intelligent TDL translation gateway for Link 16, Variable Message Format (VMF), Cursor-On-Target (CoT), Joint Range Extension Applications Protocol (JREAP), Situational Awareness Data Link (SADL), and Cooperative ESM Operations (CESMO). Today, moving data between similar and dissimilar data links is a daunting task that can prove an obstacle to mission success. HUNTR is a breakthrough software application that significantly improves and simplifies the real-time translation and routing of TDLs. It provides warfighters and command and control centers with real-time access to accurate operational data in the field. HUNTR supports the automatic routing, forwarding, and translation of J-Series, K-Series, CoT, and CESMO messages and automates processing and translation of multiple, simultaneous Digitally- Aided Close Air Support (DACAS) missions between ground JTAC kits equipped with VMF or CoT radios and air/land/sea Link 16 assets. Designed to run on any Microsoft Windows 10 supported platform, HUNTR delivers instant integration and interoperability for multiple heterogeneous TDLs.

  • Military Data Link Integration Application
    Military Data Link Integration Application James T. Sturdy Honeywell Defense and Space Electronic Systems 9201 San Mateo Blvd., NE Albuquerque, New Mexico 87113-2227 (505) 828-5703 Office (505) 828-5500 Fax [email protected] 1 Abstract The military uses tactical data link radios to send and receive digital voice, data, and video between vehicles and command and control facilities. These data link radios are interfaced to various mission computers and display systems. As outlined in the Joint Tactical Data Link Management Plan, a wide range of legacy military platforms will be upgraded to incorporate new data link radios through 2015 and beyond. The upgrade costs to do this will be enormous if traditional subsystem upgrade approaches are used. A need exists for a common, scalable and low cost military data link integration solution that can be used in multiple and disparate platform applications. The author will discuss such a design approach that can be used on each military platform application. The solution processes new and evolving messages with a database driven design so that the user can control message activation, deactivation, and processing instructions for each unique platform application. The database used for this capability is created by and maintained by the user. This allows a common design to work and to evolve on each unique platform without the need to modify the operational software. Background The military uses tactical data link radios to send and receive digital voice and data between their air, land, sea and space vehicles, and command and control facilities. On each vehicle and in each command and control facility, these data link radios are interfaced to various communications/mission computers and display systems.

  • JREAP Vs SIMPLE What’S the Verdict?
    JREAP vs SIMPLE What’s the Verdict? Joint Range Extension Application Protocol (JREAP) vs Standard Interface for Multiple Platform Link Evaluation (SIMPLE) Within the capability streams for distributing Tactical Data Link (TDL) information beyond normal communication limits there exists two military standards: JREAP and SIMPLE. Military staff have therefore asked the question “Which should I implement that can support operations?”. Both are NATO standards born out of the need to distribute information beyond the typical communication limits and provide a mechanism for linking into TDL systems. JREAP was originally implemented through Military Standard (MIL-STD)-3011 but has now been adopted under NATO cover Allied Tactical Data Link Publication (ATDLP)-5.18 (STANAG 5518) and SIMPLE through ATDLP-6.02 (STANAG 5602). In short, JREAP is a deployable tactical capability whereas SIMPLE is used in a test environment. However, this article scrutinises the capabilities and implementation of each and provides a comparison of abilities to support front-line operations. JREAP was developed due to the need to communicate data over long distances, i.e. Beyond Line of Sight (BLOS), without degradation to the message format or content. JREAP takes the message from the format it was originally in and encapsulates it within a JREAP wrapper so that the message can be transmitted over BLOS media and to those platforms not equipped with traditional Link 16 equipment such as Multifunctional Information Distribution Systems (MIDS) terminals. If one was to examine the history of JREAP publications the first MIL-STD-3011 issue is a cut down version of STANAG 5602 Edition 1 with additions to operate over a number of specified communication bearers.

    APPENDIX A. TACTICAL DIGITAL INFORMATION LINKS A tactical digital information link (TADIL) is a Joint Staff-approved, standardized communications link TADIL-C that transmits digital information. Current practice is to characterize a TADIL by its standardized message formats and transmission characteristics. TADILs TADIL-C is also known as Link 4A. It is an unsecure, time-division digital data link conducted between an interface two or more command and control or air defense controlling unit; e.g., TAOC or airborne weapons systems via a single or multiple network warning and control system (AWACS) and architecture and multiple communication media for appropriately equipped aircraft.

Military Equipment and Technologies Research Agency Abstract: Tactical data links (TDL) are elements of C4ISR system, which provide a continuous data exchange in (nearly) real time about space, ground, air, surface and subsurface platforms including allied, neutral and foe units data. The main scope of TDL is to provide the operation monitoring capability (for commander) and to send particular commands and data (for subordinates), being one of the basic components of network centric warfare concept implementation. A TDL uses data link standards in order to provide communication via radio waves or cable to transmit, relay and receive tactical encrypted data. This paper aims to outline a comparison between the main TDL standards and their capabilities. Key words: tactical data link, Link 1, Link 11, Link 16, Link 22 1.
