DESCRIPTION AND OPERATION
Heading
The heading gives the user the direction in which the
vehicle is pointing. The heading is displayed on the
full guidance screen to the nearest whole degree
starting at 0 degrees and is updated as required when
dictated by an ’event’. The heading is updated at the
same time as the bearing.
GMT 24 hour
The GMT 24-hour clock time is shown on the full
guidance screen and is taken directly from the GPS
data and cannot be adjusted by the user.
Altitude
The accuracy of the altitude is 50 metres or 150 feet
depending on the system settings. The altitude is
displayed on the full guidance screen even if the latest
altitude data is not available. If valid altitude data is
not available, the last known altitude is displayed. The
altitude is updated as required when dictated by an
’event’. The altitude is updated at the same time as
the bearing and heading.
Current Car Position Icon
The current car position is the same as is used for
road navigation. The Current Car Position icon has an
accuracy of 15 degrees starting with 0 degrees. The
Current Car Position icon is updated as required when
dictated by an ’event’.
Current Co-ordinates
The current co-ordinates are shown on the selected
guidance screen. The current co-ordinates are the
coordinates of the current vehicle position in the
format selected in the settings menu option. The
resolution of the co-ordinates is to be such that the
least significant displayed digit remains as close as
possible to the calculated vehicle position. The current
co-ordinates are updated at the same time as the
heading and bearing.
Distance to the Destination
The distance to the destination is shown on the
selected guidance screen. The distance to the
destination is the direct point to point distance from
the current vehicle position to the destination
(waypoint) in the selected system settings. The
distance to destination is updated as required when
dictated by an ’event’. The distance to destination is
updated at the same time as the heading and bearing.
Arrival at Destination (waypoint)
When a waypoint is achieved and the guidance
screen is updated to direct the user to the next
waypoint of the route, the following items are updated
for the new waypoint:
•
Waypoint reference number
•
Waypoint title
•
Destination arrow
•
Destination co-ordinates
•
Distance to destination
•
Bearing to destination.
If the waypoint is the final waypoint of the route or the
destination is not part of a route, the existing guidance
data remains active.
