GBR 23

Part Number: 010-00151-00


Developed in response to market demands for greater GPS accuracy, Garmin's GBR 23 receiver corrects for Selective Availability (SA) (in the event that this is ever recommissioned by the U.S. Government) and atmospheric error, enabling an accuracy of 1-5 meters.

The GBR 23 is a remote, auto-tuning, differential beacon receiver with a built-in H-field antenna. The perfect companion to any Garmin® GPS receiver, the GBR 23 provides position correction data to all Garmin differential-ready, marine, and recreational GPS receivers, including select products made by other manufacturers. The GBR 23 is a replacement product for the current GBR 21.
