These were obtained from American-MilSpec
but there's not much
info available on them.
If you know anything about these please let
These may be part of one of the following systems:
REMBASS - Remotely Monitored Battlefield Sensor System - uses
Passive IR, Magnetic, Seismic, CCD Camera (not IR beam & not
Friendly Fire (Wiki):
"There is also some development of remote sensors to detect
enemy vehicles – the Remotely Monitored Battlefield Sensor
System (REMBASS) uses a combination of acoustic, seismic vibration, and
infrared to not just detect, but identify vehicles." I
wonder if this capability really worked?

Tactical Remote Sensor Systems
(TRSS) System-of-Systems (SoS) has the following components:
Unattended Ground Sensor Set (UGSS),
A suite of hand emplaced sensors that operate unattended and
detects activity through seismic, acoustic, infrared, and magnetic
sensing technologies. The UGSS primary sensor is the
Encoder-Transmitter Unit Version II (ETU-II).
- The ETU-II is a low-resolution, seismic-acoustic target
classification sensor which reports targets as wheeled
vehicles, tracked vehicles, or personnel.
- Each UGSS includes 50 Infrared Intrusion Detector, Version
IIs (IRID-II) and
- Magnetic Intrusion Detectors (MAGID) that can be attached to
the ETU-II to provide additional target discrimination and
- The IRID is a temperature-sensitive transducer that reports
changes in its observed field of view and reports the
direction of the activity it is traveling.
- The MAGID recognizes changes in its near-field magnetic
environment and reports direction of movement.
Day/Night Imager Version II, AN/PSQ-21
An integrated system of cameras, radios, and image processing
hardware that captures and transmits images from areas under
surveillance to distant sensor monitoring systems. Upon detection
of sufficient pixel changes in the Field of View (FOV), the Imager
captures an image. The Imager then uses its radio systems to send
the image to sensor monitoring sites either directly, satellite
communications, or via one or more Radio Repeaters. The Imager is
remotely configurable to change operational modes, select camera
controls, and change radio frequencies.
Hand-Held Programmer-Monitor (HHPM),
A portable, programmable, dual-band, sensor emplacement tool for
programming sensor equipment, monitoring sensor activity,
recording sensor positions, and testing Radio Frequency (RF)
communications paths between remote device sites. Sensor imagery
is displayed in the HHPMs Tactical External Viewing Assembly
(TEVA). The TEVA may also be connected directly to the TRSS Imager
when the user desires to see a cameras field of view. The HHPM
menu provides a variety of user-selectable display preferences and
test messages designed to enable Marines to perform sensor tests
and direct (cabled) reconfiguration at sensor emplacement sites.
An earphone assembly and night vision filters are provided to
enable operation when light and sound discipline is required.
Radio Repeater Set, AN/GRQ-32
A dual-band sensor retransmission system that enables
communication between deployed sensors and monitoring sites when
direct sensor-to-monitor radio line-of-site is precluded by
terrain. The Radio Repeater is remotely configurable to use
various modes, filter messages, mask out problematic sensors, and
change operating frequencies.
3 Socket Connector
The mating connector is the PT02A-8-3S.
