2. Усталёўка і ўстаноўка драйвера

Before using the GPS module, ensure proper driver installation for your operating system. For optimal signal reception, place the module in an area with a clear view of the sky, such as near a window or outdoors, free from obstructions like buildings or trees.

2.1 Windows Operating Systems (XP, 7, 8, 10)

1. Connect the USB GPS module to an available USB port on your computer.
2. Адкрыты Дыспетчар прылад. You can typically find this by searching in the Start Menu.
3. Look for an unrecognized device or a device under 'Ports (COM & LPT)' that indicates a USB Serial Port. It might appear as 'Prolific USB-to-Serial Comm Port' or similar.
4. If the driver is not automatically installed, you may need to download it from the manufacturer's webсайт. Пошук 'Prolific USB-to-Serial Comm Port driver' or refer to the product's support page for specific driver links.
5. Right-click the device in Device Manager and select 'Update driver'. Choose 'Search automatically for drivers' or 'Browse my computer for drivers' if you have downloaded the driver package.

2.2 Linux and Raspberry Pi

For Linux-based systems, including Raspberry Pi, the module typically operates without requiring additional driver installation. It should be detected as a serial device (e.g., /dev/ttyACM0).

1. Connect the USB GPS module to your Linux or Raspberry Pi device.
2. Verify device detection using commands like ls /dev/tty* or dmesg | grep tty.
3. You may need to install and configure gpsd or other GPS-related software to interface with the module.

2.3 External Antenna Connection

The module includes an IPEX interface for connecting an optional external antenna, which can improve signal reception in challenging environments.

3. Operating the Module with u-center Software

The u-center software (from u-blox) is a common tool for configuring and monitoring GNSS modules. It provides detailed information about satellite reception, position, and various settings.

3.1 Installing u-center

Download the u-center software from the official u-blox webсайт: https://www.u-blox.com/en/product/u-center-windowsВыконвайце інструкцыі на экране, каб завяршыць усталёўку.

This screenshot displays the u-center software, showing various panels for satellite signal strength, NMEA data output, and geographical position, used for monitoring and configuring the GPS module.

3.2 Connecting and Monitoring

1. Launch u-center.
2. У радку меню абярыце Receiver > Port and choose the COM port assigned to your USB GPS module (e.g., COM3, COM4).
3. Ensure the baud rate is set correctly. The default output is the product GPS protocol data. You can test the software or serial commands to modify switch PS / GLONASS protocol data.
4. Once connected, you should see NMEA data streaming in the 'Text Console' window and satellite information (signal strength, position) in other panels.

4.1 No GPS Fix / Solid Red Light

If the module's indicator light is solid red and not blinking, it indicates that a GPS fix has not been acquired. This usually means the module is not receiving sufficient satellite signals.

• Relocate the Module: Move the module to an area with a clear, unobstructed view of the sky. This could be near a window, on a balcony, or outdoors.
• Знешняя антэна: If you have an external antenna, ensure it is properly connected to the IPEX interface and placed in an optimal position.
• Час чакання: Allow several minutes (up to 15 minutes for a cold start) for the module to acquire satellites and establish a fix.

4.2 Driver Issues (Windows)

If the module is not recognized in Device Manager or shows an error, the driver might be missing or corrupted.

• Reinstall Driver: Follow the steps in Section 2.1 to reinstall or update the driver.
• Check COM Port: Ensure you are selecting the correct COM port in your GPS software (e.g., u-center).

4.3 Software Not Receiving Data

If the module is connected and drivers are installed, but your software (e.g., u-center) is not displaying data:

• Verify COM Port and Baud Rate: Double-check that the correct COM port and baud rate (e.g., 4800, 9600, 19200, 38400, 57600, 112500 bps) are selected in your software.
• Single Application Access: Ensure only one application is attempting to access the GPS module's COM port at a time. Close any other software that might be using the port.
