Joint Electromagnetic Spectrum Operations

Joint Electromagnetic Spectrum Operations (JEMSO) involve coordinated efforts by military and government agencies to manage and utilize the electromagnetic spectrum—used for communication, navigation, and sensing—to achieve strategic and tactical objectives. This includes protecting friendly signals, disrupting or denying enemy use, and ensuring reliable electromagnetic access across all military branches. Think of it as a synchronized game of control over invisible signals—like radio waves, radar, and satellites—to enhance situational awareness, communication, and overall mission success while countering adversaries’ efforts to interfere or jam signals.
