Software

Configuration Steps

• Default protocol: UBX over UART or USB
• Configurable using u-blox u-center software
• Supports:
  • RTK positioning (Base/Rover mode)
  • GNSS constellation selection
  • NMEA/UBX message configuration
  • Output rate and dynamic model tuning
  • Spoofing/jamming detection

Integration Steps

1. Connect VCC (3.3 – 12 V) and GND to your power source.
2. Connect UART or I²C lines to your autopilot or telemetry system.
3. For RTK: connect to RTK correction source via UART or telemetry radio.
4. Mount securely to the frame using M3 bolts and spacers.
5. Configure using u-center or your autopilot’s GPS driver.
