Commonly called UGS and I-UGS, ground and subsurface sensors form a remote monitoring device. They are seismic, acoustic, magnetic, electro-optical (EO) and infrared (IR active / infrared passive (PIR) sensors that can detect, locate and classify targets. They provide enhanced threat warning and situational awareness and are typically implemented in battlefield situations. In the context of remote monitoring, they ensure, thanks to their automation, the collection and transmission of data to another point for evaluation.
In the C5ISR program, they will be used as remote monitoring systems that detect, identify, and track activity and subjects in hard-to-reach areas in concert with other technologies. These sensors are manually installed, fixed but removable, easily concealed, and adaptable to many operational environments. Additional detection capabilities include radar, microwave, photoelectric, contact closure and many others. Imaging UGS (I-UGS) provides photo or video verification of detections and enables advanced image analysis.
