Retrieve Position Information; Route Guidance - Vertu Constellation Quest Reference Manual

GPS Data
Select Menu > Applications > GPS > GPS data.
GPS Data is designed to provide route guidance information to a selected destination,
position information about your current location, and travel information, such as the
approximate distance to the destination and the approximate duration of travel.
GPS coordinates are expressed in degrees and decimal degrees format using the
international WGS-84 coordinate system.
To use GPS Data, your device's GPS receiver must initially receive position
information from at least four satellites to calculate the coordinates of your location.
When the initial calculation has been made, it may be possible to continue calculating
the coordinates of your location with three satellites. However, the accuracy is
generally better when more satellites are found.

Route guidance

Select Menu > Applications > GPS > GPS data > Navigation.
Start the route guidance outdoors. If started indoors, the GPS receiver may not
receive the necessary information from the satellites.
Route guidance uses a rotating compass on the device display. A red ball shows the
direction to the destination, and the approximate distance to it is shown inside the
compass ring.
Route guidance is designed to show the straightest route and the shortest distance to
the destination, measured in a straight line. Any obstacles on the route, such as
buildings and natural obstacles, are ignored. Differences in altitude are not taken into
account when calculating the distance. Route guidance is active only when you move.
To set your trip destination, select Options > Set destination and a landmark as the
destination, or enter the latitude and longitude coordinates.
To clear the destination set for your trip, select Stop navigation.

Retrieve position information

Select Menu > Applications > GPS > GPS data > Position.
In the position view, you can view the position information of your current location. An
estimate of the accuracy of the location is displayed.
To save your current location as a landmark, select Options > Save position.
Landmarks are saved locations with additional information; they can be used in other
compatible applications and transferred between compatible devices.
Trip meter
Select Menu > Applications > GPS > GPS data > Trip distance.
The trip meter has limited accuracy, and rounding errors may occur. Accuracy can
also be affected by the availability and quality of GPS signals. To turn trip distance
calculation on or off, select Options > Start or Stop. The calculated values remain
on the display.
Use this feature outdoors to receive a better GPS signal.
To set the trip distance and time and average and maximum speeds to zero, and to
start a new calculation, select Options > Reset. To set the trip meter and total time
to zero, select Restart.
Positioning settings
Select Menu > Ctrl. Panel > Settings > General > Positioning.
To use a specific positioning method to detect the location of your device, select
