Core Avionics Master Plan - NAVAIR - U.S. Navy

Core Avionics Master Plan 2011 Appendix A-2IW Phase I (2012) Phase I will provide only pre-planned pre-assigned services asdescribed in MIL-STD-188-181C and MIL-STD-188-183B. The near term SATCOMcapacity enhancements of IW Phase I will be accomplished by upgrades to existingDAMA SATCOM terminals (software upgrade to ARC-210 Gen 4 and 5).IW Phase II (2015) Phase II will add pre-planned demand assigned and ad hocservices as described in MIL-STD-188-182B. While these features will not increase thesimultaneous user capacity, the effective capacity will increase because users willrelease resources when they are not in use. Phase II will also add Common InteractiveBroadcast (CIB) software for support to the Integrated Broadcast Service (IBS).Common Threat Broadcast (Integrated Broadcast Service - IBS / Commoninteractive Broadcast - CIB). (2015) IBS is an integrated, interactive intelligencedissemination system that provides vital situational awareness and rapid threat warninginformation to the warfighter. IBS replaces and integrates services provided by variouslegacy intelligence broadcasts, including IBS-LOS (formerly Tactical ReconnaissanceIntelligence Exchange System - TRIXS), IBS-S (Tactical Related Applications DataDistribution System - TDDS) and IBS-I (Tactical Information Broadcast Service -TIBS),with CIB. Switchover to the IBS-CIB is planned to begin in 2012. Since IBS-CIBconsolidates prior IBS systems, they will cease operation once enough IBS-CIB capableterminals are fielded. Cut-over will occur in 2015 and no legacy broadcast support iscurrently anticipated beyond that date. The P-3, E-2C, EA-6B and EA-18G have areceive-only IBS requirement and use MATT receivers. The EP-3E uses theCommander's Tactical Terminal/Hybrid Receiver (CTT/HR) because it requires atransmit capability as an information provider. Neither the MATT nor the CTT/HR can beeconomically upgraded to run the new IBS-CIB and its associated crypto, and are nolonger in production. The EA-18G is separately pursuing a receive-only variant of theJoint Tactical Terminal (JTT-IBS), which will require a hardware and softwaremodification to run CIB. The EA-6B and E-2C receive-only platforms are buying theUniversal Serial Bus – Embedded National Tactical Receiver (USB-ENTR) with SmartMount to provide the full capability that the MATTs currently have, with the ability to besoftware upgraded to the CIB at the appropriate time. All MATTs are planned bereplaced prior to 2015 for most platforms except the EA-18G, which may requirecontinued operations out to 2018. The EP-3E abandoned their original plan to replacetheir CTT-HR with the JTT-IBS, and plans to access the IBS Network through SIPRNETusing broadband SATCOM connectivity. The P-8 is also investigating the feasibility ofusing this method to receive IBS information, but may consider installing the USB-ENTRstarting in 2018.Increased Throughput and Access (Mobile Users Objective System - MUOS).(2018) MUOS is the next generation of tactical narrowband UHF Military SATCOM andis the replacement constellation for UFO. MUOS will enable world wide BLOS IPconnectivity to the Defense Information Systems Network (DISN)/GIG. MUOS satelliteswill have two communications payloads: a legacy UFO payload and a MUOS payload.The MUOS satellites‟ legacy payloads will extend the useful life of the legacy terminalspast the UFO constellation end of life. This will allow for a gradual transition to theMUOS Wideband Code Division Multiple Access (WCDMA) waveform.A-2 Information Exchange 11
