Simrad ES80 Reference Manual
•
NMEA VTG
The NMEA VTG datagram contains the actual course and speed relative to the ground.
•
NMEA ZDA
The NMEA ZDA datagram contains the universal time code (UTC), day, month,
year and local time zone.
Supported datagram formats for speed log information
The ES80 supports the following datagram formats for speed information.
•
NMEA VTG
The NMEA VTG datagram contains the actual course and speed relative to the ground.
•
NMEA VBW
The NMEA VBW datagram contains water referenced and ground referenced vessel
speed data.
•
NMEA VHW
The NMEA VHW datagram contains the compass heading to which the vessel points,
and the speed of the vessel relative to the water.
Supported datagram formats for heading and gyro information
The ES80 supports the following datagram formats for vessel heading and/or gyro
information.
•
NMEA HDT
The NMEA HDT datagram provides the true vessel heading. The information is
normally provided by a course gyro.
•
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 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.
Supported datagram formats for motion information
The ES80 supports the following datagram formats from a motion sensor.
•
Simrad TSS1
Simrad Sounder/TSS1 is a proprietary datagram format created by Kongsberg
Maritime for heave, roll and pitch compensation. When you select this protocol, the
number of sensor variables is fixed, and there is no token associated with it.
