Radar Responsive (RR) technology was developed for the US Military at Sandia National Laboratories in the 1990s for specific long-range geolocation applications. The technology lead to the E911 system in the US (emergency geolocation with cell phones). GENTAG owns exclusively the civilian (non-military) sensor version of the technology (tested under patent 6,031,454 at Sandia). The civilian version is a lower power technology suitable for commercial civilian applications, including for use in diagnostic skin patches, cell phones and ultra accurate wide area tracking.

Radar Responsive Tags for Non-GPS Tracking Real-Time Location System (RTLS)Radar Responsive tags are extremely accurate and have been tested by the US military for “Blue Force” tracking to avoid “friendly fire. Dr. Mike Lovejoy tested and developed for the US government a wide area non-GPS geolocation technology that can locate in real time small tags with extremely high accuracy over 10 miles away. The technology, which is referred to as “Radar Responsive” tags (or RR tags), works inside buildings and therefore can geolocate items or people both inside or outside structures using stand-alone mobile geolocation “base stations” that can be set up anywhere.

Radar Responsive tags can be inserted anywhere, are permanent and are potentially very low cost. GENTAG’s focus is on hybrid geolocation technologies that combine GPS, RR tags and RFID sensors with cell phones, PDAs or other web-accessible wireless technologies to enable low cost real time highly accurate wireless tracking and sensing for virtually any industrial, consumer or Government application.

Applications of Radar Responsive Tags

Sample applications for Radar Responsive tags include locating patients with dementia, locating missing people or locating high value assets (e.g. cars) and “smart” diagnostic skin patches for vital sign monitoring and geolocation of soldiers, athletes or people working in dangerous environments over large geographical areas. Other applications of Radar Responsive Tags, including radio tracking of:

  • Alzheimer Patients
  • Diagnostic Skin Patches
  • Hospital Staff Location
  • People in Risk Jobs
  • Location of Firefighters
  • Location of Cell Phones
  • Location of Small Children and Elderly people
  • Car Rental Facilities
  • High Value Asset Location
  • Items Frequently Stolen
  • Small Boats and Fisherman boats
  • Campers and Hikers
  • Pet and Animal Tracking
