Cutting-edge GPS Device Integrated with GPS & Beacon Receiver MODEL : DGPS-220-PC
It is the availability of host-based operation that makes DGPS-220-PC different from its predecessor DGPS-220, which features automatic search for beacon stations. In addition to the automatic mode, DGPS-220-PC now offers a manual mode, an extra feature that allows users themselves to set up in their computing devices the frequencies and baud rates for beacon stations. This feature is designed mainly to provide users with enhanced flexibility in positioning without scarifying accuracy.
|
| As part of effort to free manual-operating users from the hassle of finding beacon stations available for their locations, DGPS-220-PC is shipped with a list of beacon stations located worldwide.
Essentially, DGPS-220-PC is an integrated GPS/Beacon receiver with built-in antennas, providing GPS differential corrections in NMEA-0183 format for navigation requiring high degree of accuracy.
DGPS-220-PC 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 no charge. Both GPS and Beacon receivers/antennas are built inside the enclosure, making DGPS-220-PC a single device featuring easy installation, maintenance and integrated services.
