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

Core Avionics Master Plan 2012 Appendix A-2Appendix A-2:Information ExchangeScope: This section covers hardware, software, waveforms, protocols and securitysystems that enable secure/non-secure voice connectivity and data collaborationbetween aircraft and other warfighters. Information Exchange (IE) covers a broad scopeof technologies that can be divided into physical and Networking layers. The physicallayer is categorized as Line of Sight (LOS) and Beyond Line of Sight (BLOS)communications. The IE section is divided into three subcategories and is presented inorder of the most mature technologies and capabilities to the least mature: (I) LOS InfoExchange, (II) BLOS Info Exchange, and (III) Internet Protocol (IP) Networking.Capability Evolution:Capability Capability Desired WarfightingElements Enablers Enhancements Capabilities• InteriorCommunications• Line-of-Sight &Over-the-HorizonCommunications• Networking,Distribution &Interoperability• Robustness &Security• ICS & Radios• Data-links &Protocols• IntelligentSoftware &Applications• ImprovedWaveforms• EncryptionDevices• SecureWireless ICS• Increased TDLInteroperability• Increased TacticalData Flow• Fused Multi-TDLUtilization• Multi-LevelSecurity• Network CentricCollaborative Warfare• Common Operational& Tactical Picture• Real-time PrecisionEngagement• Digital Close AirSupport• Enhanced ForceProtectionObjective: Network Centric Warfare and Information DominanceBaseline Enhancement Objectives and Transition Strategy.The primary means of tactical collaboration within Naval Aviation today involvesvoice communications. Enhanced collaborative capabilities are beginning to be fieldedusing Link 16. Advanced collaborative warfighting operations, such as Network CentricCollaborative Targeting (NCCT) will require airborne networking waveforms such asTactical Targeting Network Technology (TTNT) or an Advanced Tactical Data Link(ATDL) and network processors supporting Common Operating Environments (COE).The current state of capability in IE generally enables warfighters to communicateeffectively within the same Service group and exchange data within the same missioncommunity. Commercial competition for Radio Frequency (RF) spectrum and increasingwarfighter demands for streaming video are exceeding the spectrum allocated to DoD.To some extent, these demands are being met by using data compression, takingadvantage of more efficient coding and modulation techniques, and operating at higherfrequencies (Ku and Ka band) that require directional antennas. Operating in spectrumbelow 2 GHz enables utilization of omni-directional antennas, but these frequencies arein high demand by commercial wireless providers. Continued spectrum access is aserious challenge for DoD and will get worse as commercial enterprises’ demands forwireless data and new satellite systems continue to increase.A-2 Information Exchange 1
