9.4. Viewing GPS information
To view and monitor GPS information:
1. Select
GPS Information from the Navigation window
. Positioning information displays.
Latitude and Longitude show the positioning of the vehicle.
Easting and Northing shows the Universal Transverse Mercator
(UTM) position and zone of the vehicle. They are measured in
meters.
The grid numbers on the east-west (horizontal) axis are called
Eastings, and the grid numbers on the north-south (vertical) axis are
called Northings.
2. Select the
Vehicle Orientation
tab.
This shows altitude, heading (degrees), actual speed of the vehicle and
roll/pitch (degrees).
Roll is the left/right tipping of the vehicle.
Pitch is the forward/back tipping of the vehicle.
3. Select the
GPS Accuracy
tab.
This displays the number of available satellites, the correction age
(seconds) and the HDOP (lower value indicates better accuracy) and
HRMS (lower value indicates better accuracy).
Note : The HDOP (Horizontal Dilution of Precision) indicates the
effect on accuracy of a number of satellite sources and their geometry.
Keep the antennae clear of obstructions to maintain accurate GPS
readings.
