Loran Receivers & Related Products

Locus designs, supplies, and supports the highest quality navigation and timing products for major companies and government agencies around the world. Locus’ digital, all-in-view Loran receivers provide unparalleled performance to complement GNSS in navigation, time/frequency, and monitoring applications. Locus’ Loran receivers are eLoran ready, which means that with a software upgrade, you’ll be able to access the eLoran system when it’s operational in your part of the world. Our Loran products are grouped into four categories:

CsSync Series Receivers
Locus CsSync Loran-C receivers offer Stratum-1 timing performance indefinitely, including independent UTC generation, and can operate in deep urban canyons and densely-foliaged areas where line-of-sight blockage prevents GPS penetration. Cellular companies use Locus CsSync products, as they allow complete freedom of placement for cell base stations and provide an infinite, completely independent back-up to GPS.

SatMate Series Receivers
Incorporating adaptive filtering, digital noise blanking and other proprietary digital signal processing (DSP) techniques, Locus’ SatMate receivers provide vast oceanic and air space coverage and complete penetration into dense urban environments, regardless of ambient weather or interference conditions. SatMate can be combined with GPS receivers to form an integrated system offering the most reliable, accurate navigation performance, regardless of the application.

LAD Loran LRS IIID
Locus' LRS IIID is the most sophisticated Loran monitoring receiver in the world, and was specially designed to meet USCG specifications. It can track over 40 stations simultaneously, and replaces as many as five other monitoring receivers. The U.S. and Canadian Coast Guards use LRS IIID to monitor and control and North American Loran transmissions, and LRS IIIDs have recently been installed by the Japanese Coast Guard as well.

Antennas
Locus provides two types of antennas for use with its Loran receivers, the Locus E-Field Antenna and the Locus H-Field Antenna. CsSync and SatMate receivers can operate with either H-Field or E-Field antennas. The LRS IIID requires a special E-Field antenna that permits operation right at the Loran transmitter site.
