Interface specifications
The Flexview Multibeam sonar will interface with peripheral systems and sensors using
standard and/or proprietary datagram formats.
Supported datagram formats for position information
The Flexview supports the following datagram formats for position information.
•
NMEA GGA
The NMEA GGA datagram transfers time-, position- and fix-related data from a
global positioning system (GPS).
•
NMEA GLL
The NMEA GLL datagram transfers the latitude and longitude of vessel position, the
time of the position fix and the current status from a global positioning system (GPS).
•
GGK
This third party datagram format contains the vessel’s current position with the
assigned coordinated universal time (UTC) of position, as well as a selection of
position quality factors.
Supported datagram formats for speed information
The Flexview supports the following datagram format for speed information.
•
NMEA VTG
The NMEA VTG datagram contains the actual course and speed relative to the ground.
Supported datagram formats for heading information
The Flexview supports the following datagram formats for vessel heading and/or gyro
information.
•
NMEA HDG
The NMEA HDG datagram provides heading from a magnetic sensor. If this reading
is corrected for deviation, it produces the magnetic heading. If it is offset by variation,
it provides the true heading.
•
NMEA HDM
The NMEA HDM datagram provides vessel heading in degrees magnetic. The
datagram format is no longer recommended for use in new designs. It is often
replaced by the NMEA HDG telegram.
•
NMEA HDT
The NMEA HDT datagram provides the true vessel heading. The information is
normally provided by a course gyro.
