Tools


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.

SPECTRUM XXI

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).

STANDARD FEATURES

  • Frequency Assignment – automates the processing of request for the use of frequency resources from spectrum managers in support of authorized users. The process includes preparation and validation of frequency assignment proposals, determination of interference with the background environment, and distribution and tracking of proposals.
  • Allotment Plan Generator – creates a list of frequencies referred to as allotment plans or channelization plans. These plans are used as frequency resources for nominating proposals using the Frequency Assignment feature.
  • Interference Analysis – analyzes existing frequency assignments for potential interference.
  • Interference Report – generates a report to describe an interference problem and to provide information that can be used to resolve the problem.
  • Topographic Manager –automatically reformats Digital Terrain Elevation Data from the National Geospatial-Intelligence Agency (NGA) for use by the engineering algorithms within SPECTRUM XXI.
  • Compliance Validation- checks for compliance of frequency records with the Frequency Allocation Tables, the NTIA Manual, and the coordination requirements with Canada and Mexico.
  • Engineering Tools – collection of utilities to perform various types of analyses such as coverage and cosite analysis.
  • Electronic Warfare (EW) Deconfliction - assesses the impact of a planned electronic attack (jamming) on existing receivers during contingency operations and exercises.
  • Joint Restricted Frequency List (JRFL) – management tool used by various operational and support elements to identify the level of protection they desire to be applied to specific spectrum assets (i.e. frequencies or frequency bands) in order to preclude these assets from being "jammed" by friendly forces conducting EW activities.


VALUE TO OUR MISSION PARTNERS

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.

JOERAD-Online (JOERAD-O) 

The 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.  

STANDARD FEATURES

  • Assist in the resolution of potential hazards of electromagnetic radiation to ordnance (HERO) effects on munitions during the planning of Joint or combined operations or exercises as a pre-deployment planning tool.
  • Provides an organic, timely capability to calculate ordnance Safe Separation distances and/or emitter output levels.
  • Provides a capability for planners and commanders to plan for or experiment with various real-world scenarios involving the introduction of ordnance, emitters, and units.


VALUE TO OUR MISSION PARTNERS

JOERAD-O will enable HERO safe Joint operations by deconflicting potential interactions between ordnance systems and RF emitters.



JOINT SPECTRUM DATA REPOSITORY (JSDR)

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.

STANDARD FEATURES

The JSDR features the following spectrum-related databases:

  • Joint Equipment, Tactical and Space (JETS) Database - The JETS segment of JSDR is a DSO created and maintained resource that includes: Parametric data for DoD; commercial and coalition equipment (JETS-E); Platform data, including equipment complements (JETS-T); U.S. military unit names, locations and hierarchy (JETS-T); U.S. military unit equipment and platform complements (JETS-T); and space satellite parametric and orbital data (JETS-S); etc.
  • Host Nation Spectrum Worldwide Database Online (HNSWDO) - HNSWDO is a web-based application for processing DoD Host Nation Coordination Requests and responses.
  • Spectrum Certification System (SCS) Database – SCS is the central archive repository for all DoD Spectrum certification system data, including information from the J/F-12 Application for Equipment Frequency Allocation.
  • Background Environmental Information (BEI) Database - To accurately represent the electromagnetic environment, the DSO also collects additional non-U.S. Federal and international frequency assignments, which are stored in the BEI database. The BEI currently includes International Telecommunication Union (ITU), Federal Communications Commission, Canadian, and Radio Astronomy assignments.
