Sentry in red, sensor locations in green.

By Jeffrey Coffed and Joseph Rolli, Harris The first and best step to combat the growing worldwide problem of GPS jamming is to pursue technologies that can detect and locate the jammers. Signal Sentry 1000 uses arrayed sensors to do just that: look out for jamming and track down its source once sensed. An array of sensors can be deployed... read more

A WINS for Warfighters
