♦
Fix
It is the current position of the vessel provided by the GPS (connected to the
chart plotter or built-in) or other positioning systems.
♦
Fix Status
It indicates the quality of the position fix signal.
♦
Fuel Consumption Rate
It represents the estimated fuel consumption rate (per hour) of an engine
boat referred to its relative estimated cruising speed.
♦
GNSS = Global Navigation Satellite System
It is the name used to indicate any single or combined navigation system
based on satellites. The current available satellites systems are: GPS, GLONASS
and the combined GPS and GLONASS.
♦
Goto

under any weather conditions.
♦
HDG = Heading

Speed of the vessel relative to the water, provided by an instrument with a sub-
merged transducer for measuring the distance/speed travelled by the vessel.
♦
Longitude
The angular distance East or West of the prime meridian (Greenwich meridian)
as measured by lines perpendicular to the parallels and converging at the
poles from 0° to 180°.
♦
Loran
