4. Setup and Installation

4.1 Wiring Diagram

Proper connection to your flight controller is crucial for the GPS module's functionality. The module supports both UART (for GPS data) and I2C (for compass data) interfaces. Ensure correct cross-connection for TX/RX lines.

• UART Connection (GPS Data): Connect the GPS module's TX to the flight controller's RX, and the GPS module's RX to the flight controller's TX. Connect 5V to 5V and GND to GND.
• I2C Connection (Compass Data): Connect the GPS module's I2D to the flight controller's I2D, and I2C to I2C. Connect 5V to 5V and GND to GND.

4.2 Software Configuration (Betaflight)

Follow these steps to configure your SoloGood M10-180C GPS module in Betaflight:

1. Connect the GPS module to a free serial port on your flight controller.
2. Open the Betaflight Configurator on your host computer. Navigate to the 'Ports' tab. Enable the 'GPS' function for the corresponding UART port where the GPS is connected. Set the baud rate to 'AUTO'.

4. Save and restart the flight controller. After restarting, you should see the GPS icon lit in the Betaflight OSD or configurator, indicating satellite acquisition. For initial star search, take the aircraft to an open field.

4.3 Software Configuration (INAV)

Follow these steps to configure your SoloGood M10-180C GPS module in INAV:

1. Connect the GPS module to a free serial port on your flight controller.
2. Open the INAV Configurator on your host computer. Navigate to the 'Ports' tab. Enable the 'GPS' function for the corresponding UART port where the GPS is connected. Set the baud rate to 'AUTO'.

4. Save and restart the flight controller. After restarting, the GPS label should light up. Take the aircraft to an outdoor open space for satellite acquisition. Initial power-up identification (M0) may take approximately 30 seconds.

5. Operating Principles

5.1 GPS Data Protocol Description

The SoloGood M10-180C GPS module outputs relevant data via its serial port, supporting two primary data protocols:

About the UBX Protocol

The UBX protocol is a binary protocol that is generally more efficient and easier to parse than NMEA. Modern Ublox chips (eighth generation and later) provide PVT (Position, Velocity, Time) statements, which contain most of the information required by users. The UBX protocol offers enhanced positioning accuracy estimation values such as hAcc (horizontal accuracy estimate) and vAcc (vertical accuracy estimate), which are more valuable than the hdop (horizontal dilution of precision) and other data found in NMEA. For these reasons, most UAV flight controllers utilize the UBX protocol over the traditional NMEA. It is generally recommended to use the UBX protocol for optimal performance.

6. Maintenance

To ensure the longevity and optimal performance of your SoloGood M10-180C GPS module, consider the following maintenance guidelines:

• Physical Protection: Avoid exposing the module to excessive physical shock, moisture, or extreme temperatures.
• Interference: Keep the GPS module away from strong electromagnetic fields, especially from video transmitters (VTX) and high-current power lines, as these can interfere with satellite signal reception. A distance of at least 3-4 inches from the VTX antenna is recommended.
• Cleaning: If necessary, gently clean the module with a dry, soft cloth. Do not use liquid cleaners or solvents.

7. Troubleshooting

If you encounter issues with your SoloGood M10-180C GPS module, refer to the following common problems and solutions:

• Slow Satellite Acquisition or No Satellites Found:
  • Ensure the drone is in an open outdoor area with a clear view of the sky.
  • Verify that the GPS module is positioned away from potential interference sources, such as the VTX antenna.
  • Check all wiring connections for proper seating and correct TX/RX cross-connection.
  • Confirm that the correct GPS protocol (UBLOX recommended) and baud rate are selected in your flight controller software (Betaflight/INAV).
  • Allow sufficient time for initial satellite lock, which can sometimes take a few minutes, especially after the first power-up or if the module has been moved significantly.
• Incorrect GPS Data or Unstable Readings:
  • Double-check the wiring, particularly the TX/RX connections, to ensure they are not reversed.
  • Ensure the flight controller's GPS settings match the module's capabilities and recommended protocols (UBLOX).
  • Inspect for any physical damage to the module or wiring.
• Module Not Powering On:
  • Verify the power connection (5V and GND) from the flight controller to the GPS module.
  • Ensure the flight controller itself is receiving power.
  • Check the input voltage to ensure it is within the supported range of 3.6V-5.5V DC.
