San Jose DGPS Receiver
MODEL: DGPS-216
An integrated GPS/Beacon receiver with built-in antennas that provides differential GPS corrections in NMEA-0183 format for navigation requiring high degree of accuracy.
Overview
DGPS-216 is a combined high performance GPS receiver and a differential beacon receiver in an extremely compact and fully waterproof enclosure providing 1~5 meter DGPS positioning accuracy by utilizing the broadcasted (283.5~325KHz) GPS differential corrections from the USCG, CCG, or IALA Beacons at free of charge. Both GPS and Beacon receivers/ antennas are built inside the enclosure, making DGPS-216 a single device featuring easy installation, maintenance, and integrated services.
