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

Core Avionics Master Plan 2011 Appendix A-2II. Beyond Line-of-Sight Communications.Mandates and Milestones:Integrated Broadcast Service (IBS)/Common interactive Broadcast (CIB). (2015)Cut-over to a new waveform will occur in 2015. No legacy broadcast support is currentlyanticipated beyond that date. Platform RTs must be modified to receive the new signal.Mobile User Objective System (MUOS) Fully Operational Capability (FOC). (2015)MUOS SATCOM constellation in orbit and fully operational.Capability Element Evolution:A. Narrowband Satellite Communications (SATCOM) / Intel Broadcast.1. Current capabilities.The majority of Naval Aviation platforms utilize narrow band UHF SATCOM for theirBLOS voice. The current UHF Follow On (UFO) satellite system allocates specific,limited channels for a particular service, such as Fleet Secure Voice Common, FleetSatellite High Command Network, Tactical Information Broadcast, or Fleet Flash Net.Demand Assigned Multiple Access (DAMA) waveform is being used to managementmilitary UHF SATCOM usage. The ARC210 is typically used for voice and limited dataapplications. The Multi-mission Advanced Tactical Terminal (MATT) is used byplatforms requiring access to threat broadcast services. The current UFO SATCOMsatellite constellation is vastly over-subscribed and has outlasted its planned servicelife. Each satellite loss results in a reduction of total system communications capacity. Itis estimated that by 2015, the system will have only 40% of its current capability.2. Funded Enhancements and Potential Pursuits.Increased Access (Integrated Waveform - IW). (2011) IW is being designed as anupgrade to DAMA to increase through-put capacity by using more efficient and tightertime partitioning. IW affords a marked improvement in voice quality, available accesses(nearly threefold increase), improved link margin, and faster, more efficient, more userfriendlyterminal operation. It also enables services on UHF SATCOM networks to runhigher performance applications that require more bandwidth. An IW and DAMAstandards comparison is shown below. IW is backwards compatible with DAMA. Usersof IW can communicate with DAMA users by creating wider IW timeslots that matchDAMA timeslots. IW will eventually provide Mixed Excitation Linear Prediction (MELP)voice in an Open Systems Connection (OSI) layered approach.A-2 Information Exchange 10
