The Joint Spectrum Center (JSC), a field office within the Defense Spectrum Organization (DSO), has leading experts in the areas of spectrum planning, electromagnetic environmental effects (E3), information systems, modeling and simulation, and operations to provide complete, spectrum-related services to the military departments and combatant commands. JSC has extensive experience in applying electromagnetic environmental databases and analysis tools to assist in both the acquisition and operation of communications-electronics assets. JSC is a source of engineering expertise and services dedicated to ensuring effective use of the electromagnetic spectrum.

JSC provides services such as spectrum-planning guidance, system integration, system vulnerability analysis, environmental analysis, test and measurement support, operational support and spectrum management software development.

JSC provides support for spectrum planning, spectrum certification of new weapon and sensor system development, and training and operational support to the unified commands, military departments, and defense agencies. These services are also available to federal and local government activities. Additionally, foreign nations can obtain assistance through Foreign Military Sales (FMS) channels. JSC can provide these services to US industries when the efforts are determined to be in the interest of national security.
