The new Locus DSP based receivers elevate Loran performance standards to an unprecedented level, making the SatMate receiver the ideal complement to GPS whenever complete availability, reliability, and integrity are required.

Locus’ patented Linear Averaging Digital (LAD) Loran technology provides simultaneous tracking of up to 40 Loran transmitters with overall signal to noise improvement at least 20 dB better than conventional receivers. Incorporating adaptive filtering, digital noise blanking and DSP techniques, the SatMate receiver provides hundreds of thousands more square miles of oceanic and air space coverage and virtually complete penetration into the most dense urban environments, regardless of ambient weather or interference conditions.

Loran is the ideal complement to GPS in all marine, aviation, and terrestrial applications, and eliminates the vulnerabilities of a sole-means system. The receiver can be integrated with a GPS receiver and controlled by a single user interface, making operation cost effective and transparent to the user. Built-in Eurofix capability means DGPS corrections can be continuously supplied, whatever and wherever the need. Antennas, specifically designed to work with Locus receivers, can be ordered in optional configurations depending on the specific application. Locus will work with companies interested in compact, integrated GPS/Loran systems.
