7. FAQ’s
What is the difference between the BT-359W and the BT-359S?
There is no difference between these two models with exception to the cosmetic faceplate used. The “W” is a radio
wave patter, while the “S” has the appearance of a solar cell. Internally they are the same device.

I am not getting GPS data into my application on my Windows PC.
1.
Check your DEVICE MANAGER to confirm the COM Port number assigned to the GPS. Then be sure
this is the same COM port number configured in your application.
this is the same COM port number configured in your application.
2.
Be sure your Baud rate is configured correctly at:
Baud Rate: 38400
Data bit: 8
Parity: None
Stop Bit: 1
Flow Control: None

3. Configure the GPS Info utility with the correct COM Port and test your GPS receiver first
before using it
in your application.
Will the 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 Gloablsat 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 between 1~5 meters 2D RMS
with WAAS enabled and 10-15 meters 2D RMS WAAS disabled

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 GPS receiver. 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?
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 GPS has a
built-in LED status indicator that shows the following:

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.
