OPERATIONAL SUPPORT (J3)
The Joint Spectrum Center (JSC) Operations Division (J3) provides Communications-Electronics (C-E)/Electromagnetic Battlespace (EMB) support and Joint Spectrum Interference Resolution (JSIR) support to the Joint Staff, Unified Combatant Commands, and warfighting commanders. This support is available for both contingencies and joint training exercises and can be provided from the JSC or on-site. Please read below for more information regarding J3 services.
SUPPORT TO THE WARFIGHTING UNIFIED COMBATANT COMMANDS AND JTF COMMANDERS
The JSC Operations Division provides:
- Automated frequency management support and training, electromagnetic environmental database support, electromagnetic compatibility (EMC) analysis support, generation of the Joint Communications Electronics Operation Instruction (JCEOI), development of the Joint Restricted Frequency List (JRFL), and support to the Electronic Warfare officer and the information operations (IO) cell
- Joint Spectrum Interference Resolution (JSIR) support through analysis and deployment teams as necessary
- SPECTRUM XXI software training and joint exercise support
- Area Studies in support of Unified Combatant Command requirements
- JSC liaison and coordination support to IO cell, Joint Information Operations Center (JIOC), and Intelligence organizations as required
- Review of operations plans (OPLANS) for spectrum supportability, upon request.
ELECTROMAGNETIC BATTLESPACE AND COMMUNICATIONS-ELECTRONICS PLANNING SUPPORT
The JSC supports achieving information superiority and full spectrum dominance by providing services and products to Assistant Secretary of Defense for Networks and Information Integration (NII), Joint Staff, Unified Commands, Joint Task Forces, Military departments, and Defense Agencies to enable the DoD's effective use of the electromagnetic spectrum. Providing electronic battlespace and C-E planning support directly to the warfighter, the JSC Operations Division offers these typical services:
- SPECTRUM XXI Frequency Nomination/Assignment/Allotment
- EW Deconfliction
- JRFL Assistance/Preparation
- Interference Analysis
- Propagation Predictions (MF-EHF)
- C-E System Performance Prediction
- Radar Target Acquisition Coverage Prediction
- EMC Analyses in Support of Frequency Planning
- Topographical Analyses
- JCEOI Planning/Preparation
- Electromagnetic Environment (EME) Definition
- Geophysical Environment Definition.
JOINT SPECTRUM INTERFERENCE RESOLUTION (JSIR)
The JSIR program was established by DoD in October 1992, as a replacement for the electromagnetic interference portion of the former DoD Meaconing, Intrusion, Jamming, and Interference (MIJI) program. The focus of the MIJI program was on the reporting of potentially hostile electronic warfare attacks against U.S. military systems. The JSIR program is structured to have interference incidents resolved at the lowest possible level of the DoD component chain of command, using component organic resources to resolve interference incidents where possible. Those incidents that cannot be resolved locally are referred up the chain of command, with resolution attempted at each level.
If the interference incident cannot be resolved by the affected DoD Component or the service engineering agency responsible for spectrum interference resolution, then it is referred to the JSC JSIR office for resolution. The JSC JSIR office will analyze and attempt to recommend corrective action for reported interference problems by first using the JSC and JSIR databases and analytical tools, and then, if needed, by providing personnel and equipment to perform on-site direction finding, equipment test, and problem solution. If the assistance is requested for electronic attack incidents, the JSC JSIR office will coordinate analysis, collection, and field support activities with the appropriate agencies.
C2-PROTECT SUPPORT
The JSC Operations Division supports C2-Protect operations through each of the following activities:
- Provision of databases on friendly force C2 system location and technical characteristics data for use in planning C2-protect. The databases cover DoD, US government, and civilian communications, as well as radar NAVAIDS, broadcast, identifications, and electronic warfare (EW) systems. The databases are available on a quick reaction basis in a variety of formats and media to meet the needs of IO planners and spectrum managers.
- Assistance to the EW officer or IO cell in the development of the JRFL. The JSC provides an automated tool, SPECTRUM XXI, to assist in the development and management of the JRFL. The JSC has Unified Combatant Command support teams that deploy to the combatant command or JTF. The teams are available to prepare the JRFL or provide training and assistance in JRFL preparation. These teams are also available to provide assistance in spectrum management matters.
- Assistance in the resolution of operational interference and jamming incidents through the auspices of the JSIR Program
- Provision of databases on foreign C3 frequency and location data. This data is developed primarily from open sources
- Provision of unclassified C3 area studies. The studies are unclassified, developed entirely from open source material, and address the C3 infrastructure of over 100 countries. The studies provide information on the physical and cultural characteristics (geography, climate, and population), overview of telecommunications systems, and the frequencies used by each country. Data is provided on civilian, military, radio/TV broadcast and navigational systems. The frequency data is provided in automated form and can be used directly by spectrum management tools such as the widely used SPECTRUM XXI.
AREA STUDIES IN SUPPORT OF UNIFIED COMBATANT COMMAND REQUIREMENTS
Each year JSC produces area studies for various countries, on CD-ROM, that provide information on the physical and cultural characteristics and the civil telecommunications sector. Specific items addressed include: frequency management; broadcasting; telephone, telegraph, and telex; data communications; aeronautical communications; maritime communications; and transmission systems. Frequency allocations, assignments, histograms, and site location maps are also included. Frequency assignment data is also provided on the CD-ROM in a spreadsheet compatible format and in vertical SFAF compatible with SPECTRUM XXI.
JSC LIAISON AND COORDINATION SUPPORT TO INFORMATION OPERATIONS AND ELECTRONIC WARFARE
The JSC provides direct support to Unified Combatant Commands, Joint Task Forces, and Joint Staff Information Operations/Electronic Warfare (IO/EW) cells, and indirect support for operational military IO/EW planning provided through the JIOC, Service IO activities, and IO/EW elements of the Intelligence Community. This effort is conducted under the mission area of "supporting electronic protect missions of information warfare as they relate to spectrum supremacy". The support provided ranges from EW deconfliction analyses to supporting IO red team efforts as they relate to spectrum dependent matters.
