L-3 Communication Systems-East Introduces Improved Smaller, Lighter Unattended Ground Sensor

L-3 Communication Systems-East (L-3 CS-East), a leading supplier of unattended ground sensors (UGS), is introducing its new BAIS-i sensor – the most capable and versatile seismic sensor on the market today.

Initially developed as a capability enhancement for the US Army’s Battlefield Anti-Intrusion System (AN/PRS-9A), the BAIS-i sensor is backward-compatible with legacy US Army and US Marine Corps UGS systems, including L-3’s Remotely Monitored Battlefield Sensor System (REMBASS), Tactical Remote Sensor System (TRSS) and Local Key Management Device (LKMD) solutions.

"The BAIS-i sensor is a smaller, lighter, more capable and less expensive solution with the same highly reliable performance and rugged dependability that our customers have come to expect from L-3."

With a proven mission duration of greater than six months, the BAIS-i sensor is ideal for intrusion detection and threat classification of personnel and vehicles for small unit force protection. A single sensor provides better detection, classification range and a lower false alarm rate than similar systems, which require two sensors per implant. In addition, the BAIS-i sensor deploys quickly without any cables or spikes to bury, conceals easily and is inexpensive enough to leave behind.

"L-3 CS-East is proud to continue supporting our Army and Marine Corps customers with best-in-class capabilities," said Bob Lisowski, vice president of secure space and sensor systems for L-3 CS-East. "The BAIS-i sensor is a smaller, lighter, more capable and less expensive solution with the same highly reliable performance and rugged dependability that our customers have come to expect from L-3."

Slightly larger than a hockey puck and weighing only 8oz, each BAIS-i sensor reliably detects and classifies personnel and vehicle movement at detection ranges in excess of 75m for personnel, 250m for wheeled vehicles, and 350m for large wheeled or tracked vehicles.

An extremely low-power transceiver provides a 2km, ground-to-ground RF communications range that increases to a 10km line-of-sight range with an elevated monitoring station antenna. A companion base station receiver easily connects to any computing device running Windows® or Linux operating systems. In addition, the BAIS-i system’s two-way RF communications capability supports local and remote wireless programming or reprogramming.
