Latitude
The world standard for time that takes into account the addition or
omission of leap seconds by atomic clocks each year to compensate
for changes in the rotation of the earth. Like Greenwich Mean Time
(GMT), UTC is based on the mean solar time for Greenwich,
England, which is located on the Prime Meridian (zero longitude).
UTC time is expressed as plus or minus hours of UTC.
A graphical representation of your boat's course in a 'rolling road'
format that displays the amount and direction of cross track error
(XTE). Steering instructions on the screen tell you what correction is
needed to maintain your course and arrive at the target waypoint.
The bearing from your starting point to the current position.
Indicates the boat's actual course relative to a ground position, as
measured by the GPS. This differs from your Heading, which does

new course, the picture resets to display the new course upwards.
