GPS and eLoran timing receiver for navigation test and measurement introduced by Chronos

LYDBROOK, England, 15 Jan. 2014. Chronos Technology Ltd. in Lydbrook, England, is introducing the CTL8200 eLoran GPS UTC timing receiver to help users determine if signals from the Global Positioning System (GPS) satellite constellation are being jammed or spoofed, and to test GPS receivers in the presence of interference, jamming and spoofing signals.

The CTL8200 can be a test & measurement unit for organizations wishing to conduct long term evaluation of the health and UTC alignment of the various European eLoran navigation timing signals. In addition it enables GPS vulnerability research in the presence of interference, jamming and spoofing signals.

The CTL8200 is a combination eLoran and GPS timing receiver, which enables the user to undertake continuous simultaneous real-time evaluation and analysis of UTC as derived from both the GPS constellation of satellites and selected eLoran stations.

The CTL8200 automatically calibrates its own eLoran UTC using GPSUTC on first installation. Thereafter it outputs a UTC-aligned 1pps that is independent of GPS and immune to disruption of GPS by interference, jamming or spoofing of the GPS signal.

Moreover, since the eLoran signal is inherently resilient to the failure or downtime of any individual LORAN station, the eLoran signal can be used to determine whether the GPS signal is being spoofed.
