GPS Status
No GPS–A red circle with a slash indicates the GPS receiver is not
yet detected by your computer. This status usually displays when
initialization first begins.
Acquiring–A red blinking circle indicates the GPS receiver is not yet
receiving sufficient satellite data to determine your position. This
status displays while the GPS receiver is acquiring satellite data and
can take several minutes.
2-D–A yellow circle indicates the GPS connection is successful but
there is insufficient satellite data to determine your GPS position.
This usually indicates insufficient data for an accurate location due
to:
• Only three satellites being used
• Poor signals from the satellites.
Move your receiver to another location until you get better reception.
3-D–A green circle indicates the GPS receiver is receiving sufficient
satellite data to determine your location. When the status reads 3-D,
your current coordinates, elevation, and heading are displayed, along
with the speed you are currently traveling.
Note If you are tracking with a WAAS-enabled device, a 3-D fix
displays as "3-D DGPS."
