Intro to OPNAV ElectromagneticEnvironmental Effects(E3)/Spectrum Spectrum Limitations – Saturationand Usage Restrictions Electromagnetic Interference(EMI) Real-Time Spectrum Operations –Description and Use Summary
OPNAV E3/Spectrum Responsibilities OPNAV N2N6 (Information Warfare) is the lead for–– Sponsor E3 Program for the Navy in conjunction with SystemsCommands (e.g., Naval Sea Systems Command, and Naval AirSystems Command)––– USN E3/Spectrum policy and requirementsElectromagnetic Maneuver Warfare requirementsElectromagnetic Interference (EMI) problem prevention & resolutionFleet engineering tools for spectrum managementNuclear Electromagnetic Pulse (EMP) Survivability ProgramSponsor Operational Spectrum Management via the Navy andMarine Corps Spectrum Center (NMSC)–––Procure, coordinate, register, assign, and protect radio frequencies forResearch and Development Test and Evaluation (RDT&E) and operationaluseEnsure review, coordination, and approval of all spectrum certificationrequestsResource the annual National Telecommunication and InformationAdministration (NTIA) spectrum fees
Spectrum Limitations – SaturationCommunication, Radar, Navigation Aids, Electronic Warfare MilitaryEquipment, Commercial Spectrum UseSpectrum is finite - not enough for all users
