Rtcm Received Data - Garmin GPS 25 LP Technical Specification

4.5 RTCM Received Data

Position accuracy of less than 5 meters can be achieved with the GPS 25LP by using
Differential GPS (DGPS) real-time pseudo-range correction data in RTCM SC-104
format, with message types 1, 2, 3, and 9. These corrections can be received by the
GPS 25LP sensor board on RXD2. Correction data at speeds of 300, 600, 1200, 2400,
4800 or 9600 baud can be utilized, as the GPS 25LP automatically detects the
incoming baud rate. For details on the SC-104 format, refer to RTCM Paper 134-89/SC
104-68 by the Radio Technical Commission for Maritime Services.
