OPERATION 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.

SUPPORT TO THE WARFIGHTING UNIFIED COMBATANT COMMANDS AND JOINT TASK FORCE 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 (EWO) 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.
  • Operational coordination and electromagnetic deconfliction analysis support.
  • Area Studies in support of unified combatant command requirements when requested.
  • Review of operations plans (OPLANS) for spectrum supportability, upon request.
  • Online access to spectrum operations products including country studies, HF predictions, and topographic data via the DISA DSO JSC Spectrum Operations Support Portal.


ELECTROMAGNETIC BATTLESPACE AND COMMUNICATIONS-ELECTRONICS PLANNING SUPPORT


The JSC supports achieving information superiority and full spectrum dominance by providing services and products to the Assistant Secretary of Defense, Joint Staff, unified combatant commands, joint task forces, military departments, and defense agencies to enable the Department of Defense'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 the Department of Defense (DoD) in October 1992, as a replacement for the Electromagnetic Interference (EMI) portion of the former DoD meaconing, intrusion, jamming, and Interference (MIJI) program. The JSC JSIR office maintains the DoD central repository for EMI reports and JSIR Online (JSIRO), which contains a historical and ongoing EMI database which serves as the center for tracking all EMI events from initial report through closure. JSIRO is available on SIPRNET at http://intelshare.intelink.sgov.gov/sites/jsir.

If an interference or electronic attack incident cannot be resolved by the affected DoD component or the service engineering agency responsible for spectrum interference resolution, it is referred to the JSC JSIR office for resolution. The office analyzes and attempts to recommend corrective actions, and if needed, provides personnel and equipment to perform on-site direction finding, equipment testing, and resolution solutions.


COMMAND AND CONTROL (C2)-PROTECT SUPPORT


The JSC Operations Division supports command and control (C2)-protect operations through each of the following activities:

  • 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 (EWO) 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.
  • Operational coordination and electromagnetic deconfliction analysis support.
  • Country Studies in support of unified combatant command requirements when requested.
  • Review of operations plans (OPLANS) for spectrum supportability, upon request.

JSC LIAISON AND COORDINATION SUPPORT TO INFORMATION OPERATIONS AND ELECTRONIC WARFARE


Liason and coordination support is conducted under the mission area of, "supporting electronic protect missions of information warfare as they relate to spectrum supremacy." This support includes electronic warfare deconfliction analyses as they relate to spectrum dependent matters.
