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 ND-100S. You may need to give the

GPS a few minutes to find or get a fix its location.

How do I know if the GPS is ON?

Your USB GPS must be plugged into your laptop’s USB port to get power. If your PC is on and

the COM port was configured properly, the GPS receiver is on and receiving the streaming GPS

data. This can be verified by opening your mapping software program. In addition, the Globalsat

USB 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.

Why does the GPS not work near buildings and other tall objects?

The GPS uses satellites in the space to find out where it is. Therefore it needs a clear view of the

sky. Tall buildings and other objects that block the receiver’s view to the sky make it infeasible to

determine your location. Sometimes the satellites are not overhead but near the horizon. In these

cases the GPS must have a clear view of the horizon.
