Joint Tactical Ground Station

The Joint Tactical Ground Station (JTAGS) is the United States Army's element to United States Strategic Command's Theater Event System (TES). TES provides an integrated, in-theater, 24-hour overhead non-imaging infrared detection capability for processing and disseminating missile early warning, alerting, and cueing information data to combatant commanders and missile defense assets through the use of stereo processing of the Defense Support Program (DSP) satellite data.
