9.1.2.13 NMEA Output
Descrip- This function outputs a configurable combination of the NMEA messages GPZDA, GPGGA,
GPVTG, GPRMC, GPHDT, PASHR, GPROT, GPHEV, GPGSV, PFECGPAtt, and PFECGPHve at
v2.4
This function accepts RTCM v3 GNSS corrections messages. This allows for Differential
GNSS or RTK with the Certus internal GNSS receiver.
This function is designed for interfacing Certus with an external Trimble GNSS receiver. It
accepts data in the Trimble binary format GSOF and expects packet 0x40 with records 1,
2, 8, and 12 at rates higher than 1Hz (20Hz recommended) and optional records 9 and 34
at 1 to 2Hz.
This function is designed for interfacing Certus with an external u-blox GNSS receiver. It
accepts data in the u-blox binary format and expects message NAV-PVT at rates higher
than 1Hz.
This function is designed for interfacing Certus with an external Hemisphere GNSS
receiver. It accepts data in the Hemisphere binary format and expects message Bin1 at
rates higher than 1Hz. For Hemisphere receivers that provide heading using two
antennas, NMEA should be used instead as the binary format does not allow for
transmission of heading information.
This function accepts USBL data from a Tritech USBL. For assistance with configuration,
contact Support.
This function accepts DVL data from a Linkquest DVL. The DVL should be configured to
output in NQ1 format. For assistance with configuration, contact Support.
This function accepts DVL data in the Nortek DVL binary format. It accepts the packets
0x1B (DVL Bottom Track) and 0x1D (DVL Water Track). The recommended update rate
is 8Hz.
