PMA209 2012 Core Avionics Master Plan - NAVAIR - U.S. Navy

Core Avionics Master Plan 2012 Appendix A-2SATCOM waveform developments which maintained backward compatibility duringevolution from dedicated access, to DAMA, to Integrated Waveform (IW), MUOS willemploy a completely new waveform that is not interoperable with the legacy waveforms.This difference in waveforms and the reduction of UFO SATCOM payload capacity willimpact require some platforms to replace or upgrade their RTs in order to maintainBLOS connectivity. Gen 5 ARC-210 RTs should be able to upgrade via software loads,if the MUOS waveform integration gets prioritized and funded.The new MUOS waveform is also called the Common Air Interface (CAI). CAIadapts a commercial third generation (3G) Universal Mobile TelecommunicationsSystem (UMTS) WCDMA cellular phone architecture to a military UHF SATCOMsystem using geosynchronous satellites in place of cell towers. MUOS employs 16beams per satellite which allows for better uplink gain/downlink power and spectralreuse within the satellite footprint. Each beam supports four WCDMA carriers, whichequates to 64 WCDMA beam-carriers per satellite. A beam-carrier in MUOS isanalogous to a cell tower in the commercial UMTS. This allows for a capacity equivalentto 16,332 accesses of 2.4 kbps channels, compared to the 1078 channels available withlegacy UFO satellites using DAMA today. MUOS also implements a packet switchednetworking infrastructure for all voice and data communications using the IP suite. AllMUOS communications will be directed through the Radio Access Facility (RAF) on theground and can be routed from there to any other MUOS satellite or the DISN via theTeleport interface.There are three primary components to establishing MUOS capability: terminals,infrastructure (satellites and control facilities), and the waveform. Terminals are not partof the MUOS program and therefore not controlled by PMW-146. Instead the JTRSprogram is responsible for the development of terminals and the red side waveform. Ifthe ARC-210 program obtains funding for MUOS, it will port the JTRS developedwaveform for MUOS capability. Initial on-orbit capability of the infrastructure will beavailable at the end of Q1 FY12 with Full Operational Capability (FOC) (four satellitesplus one on orbit spare) by the end of Q4 FY15. The scheduled release of the combinedred and black side waveform is schedule for Q1 FY13.B. Intermediate Bandwidth SATCOM.1. Current capabilities. Unencrypted Commercial Satellite Services (INMARSAT).INMARSAT is a commercial satellite company that manages a geosynchronoussatellite system to enable world-wide information exchange between UHF L bandcapable terminals. It is used extensively by the US Navy for BLOS connectivity to shoresites. It provides IP connectivity (which DoD will not be able to provide until MUOS isavailable). INMARSAT also currently provides greater per user throughput and systemcapacity than MUOS will. INMARSAT satellites enable users to connect through internetor Public Switched Telephone Network (PSTN) to any location in the world via groundentry points referred to as Radio Network Controllers (RNC).INMARSAT aeronautical services: Voice, low speed data and safety communications including satellite-aided ATC;Automatic Dependent Surveillance - Broadcast (ADS-B) and Controller/Pilot Data LinkCommunications (CPDLC).A-2 Information Exchange 14
