Name Description
The fuel level of the fuel source.
The direction the boat is pointing, measured in degrees. Due to wind
and waves, the boat is often traveling in a slightly different direction
than its heading. See Course Over Ground (see COG).
The perceived temperature derived from air temperature and relative
humidity.
The course of the next route leg with respect to the current heading.
The distance traveled.
Pitch The rotation angle of the boat from front to back (bow to stern).
The latitude and longitude coordinates of the vessel position based
GPS
on the GPS receiver installation location.
Roll The rotation angle of the boat from side to side (port to starboard).
The rate at which the boat is turning, measured in degrees per second.
The number of engine revolutions per minute.
The distance from the starting waypoint on the route divided by the
time elapsed since starting navigation on the route.
The measurement of the boat's progress across a given distance
and the speed measurement provided by GPS. SOG is optimal for
navigation because accurate destination times can be derived from
this measurement.
The measurement of the flow past the boat, which may vary depending
on current speed and direction.
The detected water temperature.
The detected air temperature.
The estimated time required to reach the next waypoint on the route.
TTG is calculated using the SOG (Speed Over Ground) and DTG (Distance
to Go).
The wind angle detected when the vessel is stationary.
The wind speed detected when the vessel is stationary.
The speed of travel relative to the next waypoint on the route.
The straight-line distance of the boat from the intended Track. XTE
measures how far the boat is off course.
