Globalsat Technology USB GPS Dongle ND-100 - Manual (Page 9)

2. Will the ND-100 work with Street Map, Marine Chart or Aviation software?
Globalsat USB GPS receivers provide standard NMEA data for mapping software to use and convert
to coordinates. Data from the ND-100 should work well with most any NMEA compliant software in the
market today.
3. How accurate is the GPS?
The ND-100 is WAAS/EGNOS/MSAS capable. Units sold in North America through authorized
resellers are WAAS/EGNOS/MSAS enabled unless otherwise stated. Accuracy can be approximately
5.0 meters with DGPS active. Otherwise, precision may decrease ranging from 5.0 to 10.0 Meters CEP
without DGPS.
4. What is ideal GPS environment?
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-100. You may need to give the GPS a few
minutes to find or get a fix its location.
5. 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: No fix, searching for GPS signals.
LED FLASHING: Position fix established and GPS signals are being received.
6. Why does the GPS not work near buildings and other tall objects?
The GPS utilizes the satellite constellation orbiting the earth to triangulate positioning. Therefore, GPS
receiver requires a clear sky view. Tall buildings and other objects that block the receiver’s view to the
sky make it infeasible to determine your location. In some cases, the satellites are not overhead but
near the horizon. In these cases, the GPS receiver must have a clear horizon view.
