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.
