DBR-300 is a high performance differential beacon receiver combined with a high-sensitivity antenna in an extremely compact and fully waterproof enclosure, providing 1 ~ 5 meter differential GPS positioning accuracy by utilizing radiobeacon signals (with 283.5 ~ 325 Khz DGPS corrections) broadcast by USCG or IALA beacon stations at no charge. Both Beacon receiver & antenna are built inside the enclosure, making DBR-300 a single device featuring easy installation, maintenance, and integrated services. |
