AN/GSQ-187 Remote Battlefield Sensor System (REMBASS)
AN/GSQ-187 Improved Remote Battlefield Sensor System (IREMBASS)

IREMBASS

The Improved Remotely Monitorer Battlefield Sensor System (I-REMBASS) is an unattended ground sensor system that will detect, classify and determine direction of movement of intruding personnel and vehicles. It detects moving targets and classifies them as personnel, wheeled vehicles or tracked vehicles. The system transmits real time reports on activity within the sensor's detection radius. This system is intended to provide Divisions, Brigades and Battalions with information on activities in areas in front of the Forward Line of Troops and for rear area protection within the Division zone.

IREMBASS is a preplanned product improvement (P3I) of the REMBASS. It maintains all the current capabilities of REMBASS while decreasing the size and weight of some of the components, combining the functions of some components into a single component, and providing enhanced planning and processing functions. The IREMBASS sensors and repeaters are completely compatible with all REMBASS components.

I-REMBASS is fielded to the Special Operations Forces (SOF) for ground surveillance in deep penetration/denied area operations, in Low Intensity Conflict (LIC), and for surveillance of hostile activity behind enemy lines. Also, it is fielded to the RTSI for counterdrug operations. IREMBASS is currently fielded to the 104th Military Intelligence (MI) Battalion (BN) in support of the Task Force XXI Advanced Warfighting Experiment. The MI BNs of conventional forces receive IREMBASS sensors and repeaters as replacements for damaged, broken, or lost REMBASS sensors or repeaters.

The system consists of six major components: an IR sensor, MAG sensor, SA sensor, mini-radio repeater, a monitor programmer (M/P), and an Advanced Monitoring Display System (AMDS). A set contains eight IR sensors, eight MAG sensors, thirty two SA sensors, eight radio repeaters, three M/Ps, and one AMDS. The M/P and AMDS will eventually replace the REMBASS code programmer, PMS, SMS and SSS. The I-REMBASS utilizes either lithium or alkaline batteries and has a graphics software package in Ada for graphics display on an MS-DOS based lap top computer.

(1) Sensor, Anti-Intrusion, DT-561(A)/GSQ. This is a hand-emplaced, magnetic detecting sensor. The MAG sensor detects vehicles (tracked or wheeled) and personnel carrying ferrous metal. It also provides information on which to base a count of objects passing through its detection zone and reports their direction of travel relative to sensor. The MAG sensor uses two ID codes to signify the direction of travel.

(2) Sensor, Anti-Intrusion, DT-562(A)/GSQ. This is a hand-emplaced, SA classifying sensor. It detects targets and classifies them as unknown, wheeled vehicle, tracked vehicle, or personnel.

(3) Sensor, Anti-Intrusion, DT-565(A)/GSQ. This is a hand-emplaced, passive IR detecting sensor. The sensor detects tracked or wheeled vehicles and personnel. It also provides information on which to base a count of objects passing through its detection zone and reports their direction of travel relative to sensor. The IR sensor uses two ID codes to signify the direction of travel.

(4) Radio Repeater, RT-1175(A)/GSQ. This is an expendable/recoverable, digital/analog radio repeater used to extend the broadcast range of radio messages from anti-intrusion sensor to a M/P. It receives, processes and relays messages from either an anti-intrusion sensor or another like radio repeater. Several repeaters may be used in a station-to-station chain, one sending to another, to relay messages over a long distance.

(5) Monitor/Programmer, AN/PSQ-7. The M/P is a portable, self contained, single channel, FM radio receiver and code programmer. It receives, decodes, and displays information from the remote sensors directly or through repeaters and verifies sensor and repeater deployment. The M/P is also used to program IREMBASS sensors or repeaters, supplying the desired operating frequency, ID, mission life, ARM/TEST mode, and gain. It has an RS-232 port which provides an output for a portable computer so an optional hard-copy of sensor reports can be obtained. The M/P has a low battery indicator that indicates when the battery drops below 10.7V. A specific fielding date has not yet been established.

(6) Advanced Monitoring Display System . The AMDS is software that operates on any 486+ class personal computer (PC) that has a compact disk read only memory drive and uses Windows 95 or Windows NT operating system. The PC connects to the M/P RS-232 serial data port and provides a graphic display of the sensor data on a tactical map. The AMDS software allows the user to select a map of the region being monitored, label the emplaced sensors and repeaters, collect and display the data, and create reports based on the collected sensor messages. The AMDS software, Version 2.0.0, allows multi-channel monitoring using multiple M/Ps. It uses TIGER digitized map data for operations within the continental U.S. It interfaces with Defense Mapping Agency (DMA) standard data for operations in covered areas. It can communicate with SINCGARS via a Tactical Communications Interface Module modem. It automatically saves log files, manages a full 64 sensor identifications (IDs) per channel monitored, allows seamless archiving and restoring of mission information, and can use any printer supported by Windows. AMDS development is an ongoing effort and a specific fielding date has not yet been established.

(7) Batteries. The sensors, repeaters, and M/P use either BA-5557/U lithium or AA alkaline or nicad batteries using a special battery adapter.
