USB GPS Receiver

Driver CD-ROM with User’s Guide and test utility for WIN and Mac O/S*

WIN Users please refer to the root directory on the included CD-ROM for installation instructions and drivers.

NOTE: Your can also download WIN driver and Installation Guides at: www.usglobalsat.com/

The Globalsat USB GPS receivers requires a Windows, or Macintosh laptop computer, with a CD- ROM*, USB port, and NMEA compatible navigation software. The 3rd party mapping/navigation software may have its own system requirements, please check with software vendor for details.

*CD-ROM is required for USB driver installation and access to the User’s Guide. If no CD-ROM drive is available, files can be downloaded from the Internet at : http://www.usglobalsat.com/

Thank you for purchasing a Globalsat USB GPS receiver! Globalsat USB GPS receivers allow for real-time street navigation by using your laptop for graphical plotting and positioning of your route. Simply load the GPS driver, plug the GPS receiver into your computer’s USB port and install your own personal mapping software to begin to view your position in real-time in relation to the surrounding streets in your travel area.

You’ll find that almost any NMEA compliant mapping/charting software will be compatible with your USB GPS receiver. Visit our web-site for recommended mapping programs that you can use.

http://www.usglobalsat.com/faq_details/Mapchart.asp

These are only a few simple steps that you need to follow before using your USB GPS receiver:

Install the USB driver and onto your laptop from the included CD-ROM or download the files from our web-site www.usglobalsat.com

Plug-in the GPS receiver into your laptop.

NOTE:

From within your mapping, or navigation software (including the supplied GPS Information utility), you will need to manually configure the selection of the COM port to what was assigned to the GPS receiver so that proper communication between the GPS receiver and mapping program can occur. Most all software requires that you manually configure the COM port setting for any GPS device you use.

IMPORTANT:

1.    You must change the default rate setting of your mapping software ‘s Baud Rate to 4800 if this is not currently set as such otherwise GPS data cannot be received.

2. Set Baud Rate 4800, Data Bit: 8, Parity: None, Stop Bit: 1, Flow Control: None

Place the product CD-ROM into your CD-ROM drive.

Auto-run should detect the CD bring up the following screen below.

Click on the button titled “WINDOWS USB Driver” from the main screen as shown above.

Or should your “Auto-Run” be disabled on your PC, use Windows Explorer or File Manager to locate the file titled “PL-2303 Driver Installer.exe” in the \WIN\USB Driver\ directory of the CD- ROM and click to launch the install process.

You will see this file.

Please double click on “PL-2303 Driver Installer.exe” to begin installation. Follow the instruction to complete the installation process.

Once your USB Driver has been installed, you will need to confirm which COM Port your PC has assigned to it in order to properly configure any software that will be utilizing the GPS data being received.

Your USB GPS MUST be plugged into your USB port at this time.

Using Window’s Control Panel, select System > Hardware > Device Manager

Then look under the heading of: PORTS (Com & LPT)

There should be a listing for: Prolific Serial-to-USB Comm Port (COM x)

(“x” will actually be the number your PC has assigned the USB GPS receiver).

Once you have identified the COM port number, any software that you utilize must be configured to read GPS data from this COM port.

We strongly suggest that you first test your USB GPS with the included GPS Info utility program to confirm that the GPS receiver if functioning properly on your PC and that you have successfully configured the right COM Port setting. Once this has been done, close the GPS Info program and start your application for COM port configuration.

NOTE: By default, your PC will not allow you to run multiple applications from a single COM port. It is important that you close any previously opened GPS application before switching to another GPS application as the GPS receiver and data will not be found by the new program.

There are special utilities available to split data into multiple COM ports for use by more than one application simultaneously. (see: http://franson.com/gpsgate/ )

Before using your USB GPS receiver for navigation (especially for the first time), the receiver must obtain a local GPS fix (coordinates) of the current position. To do this, take your laptop (with your USB driver and the mapping software loaded and configured) to an open area that has a clear view to the sky (such as a park or empty field). Start your software (or the included GPS Info utility program) and wait for initialization of the GPS to complete. This may take a few minutes depending on various factors such as the distance of the current coordinates from the last time the GPS receiver was activated, GPS signal strength and surrounding terrain (tall trees and buildings can block the satellite signals). Once the RAW GPS data is displayed onto the screen, if applicable for your software, a fix has been initialized (red LED on the GPS will also start to flash). In some cases initialization can take up to several minutes depending on the conditions mentioned above before complete GPS data will be displayed on the screen.

Coordinates scrolling with zero’s means that the port connection is complete, but the satellite data is not being received yet (possibly still initializing or in a bad area for satellite reception).

Once the USB GPS receiver’s driver and your personal mapping software have been installed and configured properly, you can begin to use your navigation system by plugging the USB GPS into your laptop’s USB port and launching your mapping software. If you don’t have a mapping, or navigation software, we’ve included a GPS test utility called “GPS Info” for the purpose of confirming your installation and configuration. This utility can be installed by clicking the GPSInfo.exe file from the Win directory on the CD-ROM or downloaded from our web-site www.usglobalsat.com.

LED Status indicator on the USB GPS” 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.

Always select an area in the vehicle where the GPS unit will be secure and not obstruct normal driving, visibility and safety, but still maintaining a “view to the sky” in order to receive satellite data.

It is recommended that you first load and test your GPS receiver with the GPSinfo.exe. This process will confirm you have found correct COM port number and have configured it properly.

Run GPSinfo.exe to load the utility.

Enter the proper COM port for your GPS device (see COM Port Verification above)

Set COM port to Baud rate: 4800

If no errors have been made in configuration, there should be GPS data being displayed in the window, which is confirmation that the communication between the GPS device and the “GPSinfo” software is working properly.

If there is no GPS data displayed (or data with multiple zeros in them), please exit the software and unplug the GPS receiver from the USB port and reinsert it after 10 seconds to reset the device.

The above screen shows the available satellites (numbers) and their signal strength.

USB GPS (WIN)

NOTE: Configuration (or selection) of an assigned COM port for the GPS device from within your mapping or charting software must be completed whenever using a software for the first time.

Run the file the PL-2303 Driver Installer.exe to uninstall the USB GPS driver.

I am not getting GPS data into my application.

Check your DEVICE MANAGER to confirm the COM Port number assigned to the GPS Receiver (it will be listed under the PORTS (COM & LPT) heading as Prolific Serial-to-USB Comm. Then be sure this is the same COM port number configured in your application.

Be sure your Baud rate is configured correctly at: Baud Rate: 4800

Data bit: 8 Parity: None Stop Bit: 1

Flow Control: None

Re-boot your computer and then insert the USB GPS into a USB port.

Configure the GPS Info utility with the correct COM Port and test your GPS receiver first before using it in your application.

Will the USB GPS work with other Street Mapping software?

Globalsat USB 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 USB 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?

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 BU-303. 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.

Other Comments-

Please allow an adequate amount of time for the GPS receiver’s boot-up (TTF) to complete before contacting Technical Support.
