Loran-C and eLoran Multipurpose System Monitor
The UN-154 is a multimode receiver that uses the latest version of UrsaNav’s Mitigator™ series Low Frequency (LF) receivers. The UN-154 is designed for use in differential Loran applications. The receiver, configured as a Reference Station (RS), measures and monitors Loran signals and calculates the differential corrections based on pseudo range measurements, nominal ASF values, and the surveyed location of the DLoran Station antennas. It can also act as an Integrity Monitor (IM) that pre- and post- checks the validity of the calculated differential corrections.
The UN-154 meets the stringent European Telecommunications Standards Institute requirements for Primary Reference Clocks, the Stratum–I frequency requirements, and provides traceability of time to within 50 nanoseconds of UTC. Built-in future–proofing ensures capability to track next generation LF signals with advanced waveforms and enhanced data channel capability.
