8. GPS Status
Signals are transmitted by Global Positioning System (GPS) satellites orbiting the Earth. This screen provides a visual
representation of the information being received. Latitude and longitude are displayed, along with a North-pointing
compass, the heading in degrees and ground speed. Satellites available are shown as segments.
From the Main Menu, tap GPS Status. The GPS Status screen will display
:
• Yellow Segment - a satellite is being tracked but is not being used
• Red Segment - a satellite is being used to determine a two-dimensional (2D) position fix.
• Green Segment - a satellite is being used to determine a three-dimensional (3D) position fix.
The circle under the satellite segments is green when there is a valid fix (2D or 3D) and red when there is no fix.
While a 2D fix is sufficient to maintain a valid fix, a 3D fix is more accurate.
