The Remotely Monitored Battlefield Sensor System, Version II (REMBASS-II) is the US Army's type-classified standard Unattended Ground Sensor (UGS) system that passively detects, classifies, and determines the direction of travel of intruding personnel and vehicles. REMBASS-II sensors offer exceptionally reliable performance in all environments, day and night. REMBASS-II uses three basic sensor transducers (seismic/acoustic, infrared, and magnetic) and sophisticated signal processing to achieve a high probability of detection with a very low false alarm rate. When used in conjunction with operator display software, the sensors can be used to determine the type of target, the number and direction of targets, and estimate their location and speed. The sensors communicate target data messages up to 15 km using Low Probability of Intercept/Low Probability of Detection (LPI/LPD) burst transmissions in the VHF band. Optional relay devices extend this range 15 km via a radio repeater, 150 km via an Unmanned Aerial Vehicle (UAV) relay, or worldwide via a REMBASS-II Field Processor Unit (FPU) SATCOM relay (a.k.a., REMSAT). The REMBASS-II system can accommodate new sensor types (e.g., chemical/biological, radio frequency, meteorological) with no hardware changes and downloadable software updates. Target detections are received and displayed on a small Hand Held Monitor (HHM) that is easily connected to a laptop computer to provide a graphical depiction of target activity using National Imagery and Mapping Agency (NIMA) digital mapping products. The program is sponsored by the US Army Product Manager-Robotic & Unmanned Sensors (PM-RUS), Ft. Monmouth, NJ.
