Chapter 6 presents information relating to the NMEA interface of the
Seres smart antenna. Appendix D - Resources provides contact
information should you wish to purchase a copy of the NMEA 0183
standard.
4.2.2 Binary Interface
Binary messages may be output from the Seres simultaneously as NMEA
0183 data. Binary messages have a proprietary definition and would likely
require custom software support if you wish to use it. Binary message
inherently are more efficient than NMEA 0183 and would be used when
you require maximum communication efficiency. Use of binary messages
for most users is not recommended the NMEA interface allows you to
control the operation of the Seres and also receive all necessary data
regarding status and positioning information.
4.2.3 RTCM SC-104 Protocol
RTCM SC-104 is a standard that defines the data structure for differential
correction information for a variety of differential correction applications.
It has been developed by the Radio Technical Commission for Maritime
services (RTCM) and has become an industry standard for communication
of correction information. RTCM is a binary data protocol and is not
readable via a terminal program. It appears as ‘garbage’ data on-screen
since it is a binary format and not ASCII text. The following is an example
of how the RTCM data appears on-screen:
