Throughout the acquisition process, certain tasks must be performed that involve addressing Spectrum Supportability (SS) and Electromagnetic Compatibility (EMC) issues for spectrum dependent systems. A variety of tools, databases and models are available to assist in these processes from evaluating the appropriate frequency bands for intended operation to detailed modeling of the electromagnetic environment (EME).
Electromagnetic Spectrum Management Support Tools
The Department of Navy Chief Information Officer Spectrum Team has compiled a comprehensive listing of products available across the Department of Defense. The "Electromagnetic Spectrum Management Support Tools" webpage listing includes capabilities, features, and points of contact, providing DoD spectrum workforce end-users with information regarding a wide range of Electromagnetic Spectrum (EMS) tools available to them. The
tools listed can assist in effective EMS analysis and decision making, Radio Frequency Interference (RFI) mitigation modeling, Aggregate Interference (AI) modeling, and RF risk management. (Requires a CAC card)
SPECTRUM XXI is a client/server, Windows-based, software system that provides frequency managers (FMs) with a single information system to address spectrum management automation requirements. SPECTRUM XXI supports operational planning and management of the radio frequency spectrum with an emphasis on assigning compatible frequencies and performing spectrum engineering tasks. SPECTRUM XXI is the Joint standard system for spectrum management throughout the DoD. It has also been adopted by the National Telecommunications and information Administration (NTIA) for processing frequency records for Federal agencies. SPECTRUM XXI was also provided to over 22 foreign nations through Foreign Military Sales (FMS) and these efforts have paid off with SPECTRUM XXI being used by all NATO International Security Assistance Forces spectrum management elements in the Afghan Area of Operations. The DSO Systems and Technology Branch (OS33) is the SPECTRUM XXI office of primary responsibility (OPR).
SPECTRUM XXI addresses the automated spectrum management requirements processes of the Combatant Commands, Joint Task Force, Services, and the sustaining-base elements. The resulting benefit is interference-free frequencies for the battlefield use while also ensuring that coordination of frequency assignments through national and host nation approval continues.
No service-level agreement is required.
Joint Ordnance Electromagnetic Environmental Effects (E3) Risk Assessment Database - Online (JOERAD-O) is a software tool that provides the necessary information to manage the conflict between introduced ordnance and radio frequency (RF) emitters used in Joint operations. The complex environment and accelerated tempo of Joint tactical operations demand full situational awareness and capabilities to evaluate risks associated with the RF sensitive ordnance. These ordnance items, if not analyzed, can pose a great threat to personnel and equipment or result in excessive emission controls on essential shipboard equipment. JOERAD-O is a key tool for success in Joint operations for the warfighter.
JOERAD-O will enable HERO safe Joint operations by deconflicting potential interactions between ordnance systems and RF emitters.
The Defense Spectrum Organization (DSO) has been chartered to collect, standardize, and distribute spectrum-related data. To fulfill this mission, the DSO provides direct on-line data access to the Joint Spectrum Data Repository (JSDR) or provides customized reports. The JSDR contains DoD, national, and international spectrum-related information up to the Secret level and can be accessed via the Joint Spectrum Center Data Access Web Server (JDAWS) tool. JDAWS provides user access to the database components of JSDR except Equipment Location-Certification Information Database (EL-CID).
EL-CID information is currently available through the Global Delivery Service, Netstorage. Enhancements in the coming years will provide additional data sources, data quality assessments, and universal query of organic and federated data sources. JSDR will be accessible on both the NIPRNet and SIPRNet through attribute-based access controls to ensure availability.
The JSDR features the following spectrum-related databases:
The JSDR provides DoD and its mission partners with direct online access to comprehensive, relevant, accurate, and trusted spectrum data, used to characterize spectrum-dependent systems characteristics and define the electromagnetic environment.
