The PX4 team is happy to announce a new version of the PX4 Autopilot, v1.12. After ten months (10) of hard work with more than three thousand commits from 154 contributors, PX4 v1.12 is finally out, with lots of significant improvements, new features, and tons of new hardware compatibility. For v1.12, the team focused on improving core functionality, stability, performance, and hardening failsafe operations for all supported vehicles.
How to get the release
You can try the latest release (and older ones) directly from GitHub, you can build the source, or try the pre-built binaries that can be found now on the GitHub releases for the PX4 Autopilot repository (see links below).
You can also load v1.12 directly into your supported flight controller of choice using QGroundControl, through the same procedures as before (see the link to the documentation below).
What’s in v1.12.0 stable
- Multi-EKF enabled by default (STM32F7 & STM32H7)
- Gyro dynamic notch filtering with onboard FFT
- Optimized rate control sensor pipeline
- Faster and more robust Magnetometer calibration
- New soft iron calibration coefficients
- Automatically determine the rotation of external sensors
- Added support for IRC Ghost, including telemetry
Multi-EKF enabled on F7 & H7 based boards.
Multi-EKF has been available since October 2020 on PX4 but was off by default and only available to however configured their boards to take advantage of the feature. Starting with v1.12, you can expect multiple instances of the EKF to be enabled by default taking advantage of flight controllers with 2 or more IMUs. You can read more about this feature on PR#14650 and PR#16507.
Dynamic notch filtering
We add dynamic notch filtering to the gyro control data with up to 6 frequencies per axis, updated with estimated peak frequencies PR#16385.
