Bearing

Compass—The Compass needle turns to represent the current bearing while tracking.

Coordinates—The coordinate fields display based on the selected Units preference.

Elevation—Displays the current elevation if the GPS status is 3-D and is based on the

selected Units preference. Elevation can be displayed with a 2-D status; your position is

indicated accurately on your screen as you travel unless you are in an area where your

elevation varies greatly.

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 1) only three satellites being used or 2) 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."

Under the GPS status icon, click Sat. Info to view the current satellite status.

Note: Satellite Info is a toggle button, which switches to Status. Click Status to return to the original Status dialog

area.

The Dilution of Precision area lists your Position Dilution of Precision, your Horizontal

Dilution of Precision, and your Vertical Dilution of Precision.

The Satellite Listing window displays the satellites that are currently visible in the

sky. The columns list the satellite number, elevation, azimuth, and signal-to-noise

ratio.

Note: Satellite Listing information is only available for DeLorme receivers and

NMEA-compatible receivers.
