Communication Automation
Abstract
The Battle Force Tactical Network (BFTN) on each surface, subsurface, air, or fixed US Navy platform uses previously installed existing Line of Sight (LOS)/Extended Line of Sight (ELOS) radios (a.k.a. Radio Frequency (RF)) to create a secure gateway that inter-connects all users into a common RF Tactical Network (a.k.a. wireless). Battle Force Tactical Network (BFTN) enables war-fighters to digitally communicate NATO and US-Only information necessary to execute and plan in a real-time operational environment without relying on ashore application server interaction. This RF Network separately supports US-Only and Allied/Coalition users within each platform to distribute information even if SATCOM channels to shore are lost. As a result, Carrier and Expeditionary Strike Group Commanders maintain the digital communication ability to execute and plan with other U.S. ships, submarines or aircraft, as well as with Allied/Coalition networks; even if SATCOM channels to shore are lost. In an Anti-Access Area Denial (A2AD) event, adversaries covertly jam or disable communications necessary to Fleet protection and tactical operation. In an effort to bolster Battle Group mission objectives for "information dominance" in a satellite denied environment, Battle Force Tatctical Network modem and controller engineering change enhancements [BFTN(e)] will increase High Frequency Internet Protocol (HFIP) data rates from 9.6Kbs to 128 Kbs (per channel) and concurrently increase Ultra High Frequency Internet Protocol (UHF) data rates from 64Kbs to 1.9Mbs. By automating BFTN (e) communications relays and network aware link establishment (NA-ALE) across battle groups and adding Unmanned Aerial Vehicles (UAV), the ranges of BFTN service levels can be extended for theatre of operations sufficient to thwart contested Satellite Communications (SATCOM) connectivity to shore servers. Enhancing BFTN [BFTN(e)] 1.92Mbps data-rates over multiple UHF circuits of 20nm range limit and multiple BFTN's 120Kbps HF circuits (200nm range limit) will support the full volume of secure military data necessary to all tactical operations. A Network Management System customized for RF Networking architectures will automate BFTN (e) Quality of Service (QoS) and Service Level Agreement (SLA) provided to the users. As a result, the enhanced BFTN [BFTN(e)] system, will self-assemble Transmission Control Protocol/Internet Protocol (TCP/IP) delivery circuits, adapt to user proximity changes due to maneuvers or operational demands and self-heal those data delivery circuits, if they are degraded or forcefully taken from the Afloat fighting force. FY14 BFTN (e) development efforts continue on a modification kit for AN/WSC-3 UHF and AN/URT-23 HF radios. Efforts continue on acquisition and system engineering documentation in support of a development Contract. Demonstrate and document techniques and procedures to use multiple 1.9Mbps UHF and 120Kbps (HF) RF Networks simultaneously with load-balancing and fail-over from SATCOM. This includes Developmental Test efforts, DoD Information Assurance Certification Accreditation Plan (DIACAP) & National Protection Center(NPC) integration in 1 simulated MQ-8 UAV BFTN(e) relay and 3 ships (nodes) with result being a successful completion of development tests. JALN-M is the Navy implementation of the JALN architecture which provides assured communications in any environment, especially A2AD. With disruption or loss of Space tier comms, JALN-M establishes and/or restores connectivity within the High Capacity Backbone (HCB) tier, the Distribution Access Range Extension (DARE) tier, and the Transition tier in accordance with the JALN Initial Capabilities Document (ICD) dated 27 August 2009 and the JALN Analysis of Alternatives (AoA) Final Report dated 31 October 2011. JALN-M is a robust, assured communications capability providing Joint connectivity via the HCB and Navy platform connectivity via a pseudo satellite DARE capability. JALN-M will use the Extended Data Rate (XDR) waveform for intra-battle group communications, a Common Data Link (CDL) waveform for the HCB cross-link capability, and will leverage enhanced UHF/HF waveforms for coalition connectivity. FY14 JALN-M development efforts continue acquisition and system engineering documentation in support of a development contract. Conduct analysis, risk reduction activities, and development of the routing, navigation, cross-link, and payload requirements. Development of the XDR payload. Trade studies and risk assessments will be completed in the areas of dynamic range, adjacent channel interference, XDR functionality, hardware RF options, security, information assurance, platform constraints, crosslink considerations, and acquisition and tracking. Risk reduction will include flight demonstrations employing the MIT/LL satellite simulator on an aircraft communicating with a surface terminal.
