F14 Id
The NMEA Station ID setting results in NMEA GGA message
output that strictly conforms to the NMEA Standard v3.01.The
NCT Station ID is a NavCom proprietary format that populates
F14 as described in the Tables below. The NavCom proprietary
input message 0x49, W12 sets F14 to NMEA Station ID or NCT
Station ID.
If 0x49, W13 B0 = 0,
Reference station ID number (0000 – 1023).
StarFire satellite IDs:
downlink_beam = 900; // User defined Satellite
downlink_beam = 100; // INMARSAT Americas
downlink_beam = 200; // INMARSAT EAME
downlink_beam = 300; // INMARSAT ASPAC
downlink_beam = 400; // PAC-C
downlink_beam = 500; // AOR-E
downlink_beam = 600; // PAC-W
If 0x49, W12 B0 = 1,
3-digit integer as denoted as XYY, where X is the StarFire
satellite beam in use, and YY is the GPS correction signal type
being used (see Tables below).

NMEA $GPGAA Field 14; Reference Station ID
The tables below detail the information contained in field 14 of the GGA message when NCT
STATION ID is chosen in message 0x49, W12 B0. Note that the Navigation Mode in field 14 is
the same as that of the message 0xB1, W22.
The format of field 14 when NCT STATION ID is chosen is a 3 digit integer value as denoted
below as XYY, where X is the StarFire™ satellite beam in use and YY is the GPS correction
signal type being used.
