This compact and cost-effective unit offers extremely accurate position fixes. It is accurate to 15 meters, and with SBAS mode activated, it's accurate to within 3 meters.

The display modes include Plotter, Nav Data, Steering, Highway, Speedometer and two customizable modes. The Steering mode provides an intuitive indication of course to steer and crosstrack-error (XTE). The Highway mode is useful when you are heading for your fishing ground or following a series of waypoints along a planned route.

The user-friendly design permits easy and straightforward operation with minimum key strokes. The system has various alarm functions to warn of arrival to or departure from a predefined area (arrival/anchor watch), XTE exceeding a preset limit, Alarm Clock and more.

SBAS, Satellite-Based Augmentation Systems

An SBAS provider furnishes GPS signal corrections to SBAS users, for even better position accuracy, typically better than three meters. WAAS, available in North America, MSAS (Multi-Functional Satellite Augmentation System) for Japan and EGNOS (Euro Geostationary Navigation Overlay Service) for Europe, those are the provider in the worldwide SBAS (Satellite Based Augmentation System) navigation system. All providers will be compatible with one another, thus providing seamless position fixes to SBAS users. Major contributors of an error in a single frequency GPS system are a receiver clock drift and signal delays by refraction. The SBAS reference stations on the earth monitor the GPS constellation and route GPS error data to the

SBAS satellite via the master earth station. The Inmarsat or communication satellite broadcasts the differential corrections to users.
