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

Core Avionics Master Plan 2011 Appendix A-4Appendix A-4Cooperative SurveillanceScope: This capability area addresses avionics that support Air Traffic Management(ATM) and cooperative Combat Identification (CID). Enabling systems, waveforms andprotocols include radio transmitters (data communication functions), flight informationand Precise Participant Location and Identification (PPLI) data-links, IdentificationFriend or Foe (IFF) interrogators and transponders, waveforms and encryption.“Cooperative” implies passive or pre-coordinated systems that trade information overtly.Specialized active, passive and covert Combat ID sensor systems are not addressed.Capability Evolution:Capability Enablers Capability Desired WarfightingElements Enhancements Capabilities• Civil Air TrafficMgt Interface• Military AirTraffic MgtInterface• CooperativeCombat ID• Interoperability• Robustness& Security• Radios• Data-links• Interrogators• Transponders• Displays• Waveforms• Encryption• Improved AirTraffic SA• ExpandedCooperative ID• Civils, Neutrals• Coalition Forces• Ground Forces• NSA CompliantSecurity• Global AirspaceAccess & Mobility• Single IntegratedAir Picture• Dominant Maneuver• Force Protection• Zero FratricideObjective: Global Mobility and Single Integrated Air PictureBaseline to Objective Transition Strategy.Military aircraft configurations must meet civil ATM mandates to guarantee access tocivilian controlled airspaces in order to transit to the area of operations. Compliance ismet by integration of Communications, Navigation, Surveillance / ATM (CNS/ATM)cockpits and capabilities. Most aircraft have been certified to meet mandate deadlinesthat have already passed. New production aircraft will be delivered with compliantsystems. The ATM functionalities that currently need to be met for operations inEuropean airspaces and United States National Airspace System (NAS) include:8.33 KHz VHF channel spacing for more discrete frequencies to manage traffic loads.Protected Instrument Landing System (PILS) to prevent FM radio station interference.Reduced Vertical Separation Minimums (RVSM) for high altitude traffic separation.Required Navigational Performance (RNP) and Area Navigation (RNAV) for selectedlevels of lateral separation in terms of nautical miles (nm).Mode Select (Mode S) Secondary surveillance radar for ground to air data-linkselective interrogation to manage increased air traffic capacity, support higher dataintegrity, reduce radio frequency interference and enable air to ground data-link.Automatic Data Surveillance – Broadcast (ADS-B) for automated GPS accuracylocation and information reporting to ground controllers.A-4 Cooperative Surveillance 1
