Urban search and rescue missions are extremely difficult to perform successfully. Limited resources, harsh weather conditions and severely damaged infrastructure are often obstacles in USAR missions.

The LifeLocator system uses ultra wideband (UWB) radar technology to improve the odds of recovering living victims of earthquakes, building collapses, flash floods, avalanches and other man-made disasters.

The LifeLocator TRx represents the fourth generation LifeLocator system from GSSI and employs new, dual receiver technology to increase survey effectiveness and accuracy.

Whether it is a natural disaster or man-made, LifeLocator® has proven to be an effective tool in detecting life signs like breathing and movement at building collapse locations. Deploy the unit to determine or rule out areas of interest; and the unit is highly mobile, meaning more of a disaster area can be covered in much less time.

Use the LifeLocator for-

  • Earthquakes
  • Terror Attacks
  • Mine Disasters
  • Building Collapses
  • Tunnel Collapses
  • Mudslides or Landslides, with debris
GSSI LifeLocator TRx system

Detection Benefits

  • The ability to accurately and non-invasively locate survivors following structural collapse –
    with the ability to “see” through debris, dust and other obstacles
  • The detection of motion as slight as shallow breathing, within seconds
  • Advanced breathing detection - with breathing rate indicator
  • Reliable non-human, non-canine USAR technology that enhances search capabilities

System Benefits

  • Dual channel antenna providing enhanced Sensor performance
  • Low power requirements
  • Continuous environmental noise monitoring to ensure optimal survey results
  • Rugged, weather and water resistant components; IP65 Rated
  • Wireless operation
  • Complies with CE regulations

Survey Benefits

  • Wireless and portable system
  • Ease of mobility over a site
  • Large field of detection
  • Unaffected by scent drift or other bio-sensitivities that affect canine detection
  • Non-invasive technology; no probes, no cables and no wiring
  • Completely safe for humans and animals

LifeLocator TRx Detection Modes

Locate View

The LifeLocator TRx has several modes to view the data. Locate view allows the users to identify life detection through a simplified display. Motion detection is illustrated by black squares and breathing detection is shown as red circles. The stronger the detection confidence, the larger the shapes appear.

The graph also displays the approximate distance to the target, note the representation of the sensor and the distance of the moving and breathing target beneath. Additionally, the lung icon indicates the target’s breathing rate.

Expanded View

Expanded view allows the user to view and interpret the raw data. An additional feature includes detection icons to indicate breathing (red circles) and motion (black squares) in the same view.

Yellow highlights indicate areas of interest. The white line represents the estimated signal floor. Users can toggle between Locate view and Expanded view in real-time with one button on the control unit.
