5. NMEA 0183 Interface
This chapter identifies the selection of NMEA 0183 command and
status query messages valid for the SBX-3 receiver.
5.1 Interface Protocols
The SBX-3 supports the following data, command, and status
protocols:
•
RTCM SC-104 differential GPS message protocol
•
NMEA 0183 standard command and status message protocol
•
NMEA 0183 proprietary command and status message protocol
5.2 Description of NMEA 0183
The RTCM SC-104 message standard discussed in Section 1.3
contains no provision for the transmission or reception of receiver
control and status information. To implement these functions, the SBX-
3 is capable of processing a subset of standard NMEA 0183
messages, along with a selection of proprietary NMEA 0183 formatted
messages.
NMEA 0183 is a communication standard established by the marine
industry. It has found use in a variety of marine electronics devices,
including ship-borne radar systems, Loran-C navigation devices, and
more recently GPS. The National Marine Electronic Association has
developed a significant number of messages specifically for use with
GPS.
The National Marine Electronics Association publishes updates to the
NMEA 0183 standard. The latest version is available by contacting:
