The Raystar 120 GPS Satellite Differential WAAS (Wide Area Augmentation System) Sensor can be used with most Raytheon navigation aids. The Raystar 120 receives GPS WAAS differential signals.

WAAS consists of a network of ground reference stations across the United States that monitor GPS satellite data. The master stations collect data from the reference stations and create a GPS correction message, taking into account selective availability (SA), GPS satellite orbit and clock drift, and signal delays caused by the atmosphere and ionosphere. The "corrected" differential messages are then broadcast through two Geostationary Earth Orbit (GEO) satellites on the same frequency as the GPS signal. The result is a DGPS system that delivers superior accuracy (under 3 meters).

The Raystar 120 tracks up to 12 satellites and 2 WAAS channels, and provides positions accurate to less than 10' 95% of the time.

The Raystar 120 is available in both SeaTalk and NMEA versions.
