Product Information

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 receiver is an enhanced development from the GAARDIAN and SENTINEL research projects using sensors with the latest eLoran receiver technology from UrsaNav, Inc. all incorporated within a single 1U 19” chassis.

Symbiotic Relationship between eLoran and GPS

The CTL8200 automatically calibrates its own eLoranUTC 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.
