APPENDIX B: GARMIN BINARY OUTPUT FORMAT Note: The following applies to all software versions of GPS 16xLVS and GPS 16xHVS. Two records are transmitted once per second by the GPS 16x series products. One record contains primarily postprocess information, such as position and velocity information. The second record contains receiver measurement information. The records are sent at a default baud rate of 9600 baud, 8 data bits, and no parity. Records begin with a delimiter byte (10 hex). The second byte identifies the record type (33 hex for a position record, 34 hex for a receiver measurement). The third byte indicates the size of the data. The fourth byte is the first byte of data. The data is then followed by a checksum byte, a delimiter byte (10 hex), and an end-of-transmission character (03 hex). Note: If RTCM-104 differential data is sent to the GPS sensor, the board will reset the Garmin Binary Output Data baud rate to the same baud rate used for RTCM-104 data. If the differential inputs are used on the GPS sensor, the RTCM-104 data must be sent to the GPS sensor at 9600 baud (preferred) or 4800 baud. RTCM-104 baud rates less than 4800 baud are not supported by the GPS sensors as it would limit bus bandwidth past the point where a onceper-second Garmin binary output data rate could be maintained.
