Will the USB GPS work with other Street Mapping software?
Globalsat GPS receivers provides standard NMEA data for mapping software to use and convert to
coordinates and should work well with most any NMEA compliant software on the market today.
How accurate is the GPS?
The GPS is WAAS/EGNOS capable, and for units sold in North America through authorized resellers,
these units are WAAS/EGNOS enabled unless otherwise stated. Accuracy can be up to 5 meters 3D
RMS with WAAS enabled and 10-15 meters 2D RMS WAAS disabled
What is ideal GPS environment?
For best results, the GPS requires an open, clear view of the sky. Buildings, covered parking areas,
tunnels and dense foliage can cause the GPS receiver to be unable to get a location fix.
If you are parked in a covered parking lot or near a tall building, it is recommended that you drive away
until you have a clear view of the sky before using the GPS. You may need to give the GPS a few
minutes to find, or get a fix on its location.
How do I know if the GPS is ON?
Your GPS must be plugged into to a USB port, PS2 port or 12VDC car lighter depending on which
cable set you have to get power. If you are outdoors, the device has been configured properly, the
GPS receiver should be on and receiving the streaming GPS data. This can be verified by opening
your mapping software program. In addition, the Globalsat GPS has a built-in LED status indicator that
shows the following:
LED OFF: GPS receiver is off (no power).
LED ON (solid): No fix, searching for GPS signals.
LED FLASHING: Position fix established and GPS signals are being received.
