ITT Exelis, Chronos Team on Offerings for Interference, Detection and Mitigation

ITT Exelis and Chronos Technology Ltd. have agreed to jointly pursue and develop product offerings for the GNSS interference, detection and mitigation (IDM) market.

Satellite-based positioning, navigation and timing (PNT) systems are vulnerable to many factors, such as signals jamming, resulting in potentially devastating system failures. The collaboration between ITT Exelis and Chronos Technology will allow both companies to respond to the IDM market by offering a set of complementary products and solutions.

“The IDM threat is real and the risks are increasing,” said Charles Curry, founder and managing director, Chronos Technology Ltd. “ITT Exelis has recognized the technological innovation driven by the GAARDIAN research project into GPS jamming and interference detection, and will bring cutting-edge innovations to enhance the GAARDIAN platform.”

GAARDIAN has largely concluded its three-year run to deliver prototype sensors and probes to detect interference and give alarms, as well as detailed analyses of the GNSS environment.
The British, European, U.S., and global economies are vulnerable, by their dependence on GPS/GNSS, to interruption of the energy supply, breakdown of communications, transport, and financial services, and potential loss of life  — all with no operational monitoring, detection, recourse, or back-up, prior to GAARDIAN and SENTINEL.

The follow-on SENTINEL is mid-way through its two-year life to take the next requisite steps:

  • Actually locating the interference;
  • categorizing it;
  • determining its extent;
  • giving a determination of trust in GNSS,
  • and addressing spoofing.

The project has a large user base in law enforcement and government.

For more than 37 years, ITT Exelis payloads and payload components have been on board every GPS satellite and have accumulated in excess of 500 years of on-orbit life without a single mission-related failure due to ITT Exelis equipment.

ITT Exelis Geospatial Systems, headquartered in Rochester, N.Y., is a global supplier of innovative night vision, remote sensing and navigation solutions that provide sight and situational awareness at the space, airborne, ground and soldier levels. Key applications include image intensification and thermal imaging; advanced power supplies; multi-spectral image systems; weather and climate monitoring; space science; intelligence, surveillance and reconnaissance; GPS-based positioning, navigation and timing systems; and image exploitation software.

Chronos Technology Limited is a world leader in timing synchronization solutions and GNSS jamming and interference detection, and is currently the lead for the UK Government sponsored SENTINEL research program, which followed on from the GAARDIAN GNSS interference detection project to research the location of GNSS jammers. Established in 1986, Chronos is a leading provider of technical solutions including time and timing for wireline and wireless telecom operators; highly versatile telecoms sync testing and monitoring systems and quality of service applications. Chronos also supplies GNSS (GPS) products from receivers for all application types including covert tracking, avionics and embedded systems, to test equipment (simulators) and GNSS infrastructure (antennas, splitters, repeaters) for the distribution of GNSS RF signals into sensitive environments. Chronos has developed a range of bespoke GPS timing products for time and frequency synchronization in power and communication systems.
