Betaflight and INAV now both have excellent integration of GPS modes and flight modes. Knowing how to set up a GPS properly will enhance your flying experience, making it safer and increasing your confidence in your aircraft.
Betaflight
In Betaflight, the GPS primarily serves one flight mode, but it also provides numerous OSD (On-Screen Display) elements during flight. To get started, you first need to choose your GPS module, which can come with various chipsets such as M8, M9, M10, and more. If you opt for a GPS with an integrated compass, it will enable the aircraft to determine its heading more accurately.

Next, you'll need to wire your GPS module to your flight controller and verify the connection. The setup process is straightforward:
Select the correct port: In the Betaflight Configurator, enable the peripheral dropdown for the port you used for the GPS connection.
Configure Failsafe settings: Navigate to the Failsafe tab, where you can set parameters such as the return speed and descent speed. It's also wise to enable additional safety options to ensure a reliable return-to-home function in case of signal loss.
INAV
With INAV, the GPS serves a more extensive role, as it is utilized for multiple flight modes in addition to the Return to Home (RTH) feature. Setting up GPS in INAV allows for a broader range of autonomous functions. Here’s how to get started:
GPS Wiring: Similar to Betaflight, connect your GPS module to the appropriate UART port on your flight controller.
Configuration: Open the INAV Configurator and navigate to the Ports tab to enable the GPS on the designated UART. Make sure to select the correct baud rate based on your GPS module specifications.
Flight Modes: After enabling GPS, go to the Modes tab, where you can assign flight modes such as Position Hold, Return to Home, and Waypoint Navigation. This enhances your flying experience, allowing for greater automation in various flight scenarios.
Calibration: Don’t forget to calibrate your compass (if equipped) and run a GPS check to ensure everything is functioning correctly before your flight.
Conclusion: Elevate Your Flying Experience
Setting up GPS in both Betaflight and INAV can significantly elevate your flying experience, allowing for more advanced features and enhanced safety. Whether you choose Betaflight for its simplicity or INAV for its comprehensive flight modes, understanding how to integrate and configure GPS will make you a more confident pilot. As you gain experience, you’ll appreciate the added capabilities that GPS offers, making your flights not only safer but also more enjoyable.
