Since the terrain estimator is constantly reset on ground, it is not necessary anymore to fuse fake measurements on ground if the range measurements are bad.370e04e2019-10-03 bresch - terrain_est: Continuously reset terrain height on ground using known clearance. This is the best estimate as we should not rely on a distance sensor while on the ground. This also helps when the drone is carried over as it avoids starting with a crazy downward distance for optical flow scaling.e09e3e12019-10-14 bresch - control: rename _range_aid_enabled to _is_range_aid_suitable rename rangeAidConditionsMet to checkRangeAidSuitabilityfac69d02019-10-14 bresch - control: refactor rangeAidConditionsMet functioneae6e8f2019-08-06 Paul Riseborough - EKF: Fix on ground yaw drift when using EKF2_MAG_TYPE = 44e946d52019-09-04 RomanBapst - implemented synthesized magnetometer Z measurement - calculate a theoretical value based on the knowledge of the direction and strength of the magnetic field vector and X/Y sensor measurements - needs knowledge about location on earth to work
PX4 Drone Autopilot
This repository holds the PX4 flight control solution for drones, with the main applications located in the src/modules directory. It also contains the PX4 Drone Middleware Platform, which provides drivers and middleware to run drones.
- Official Website: http://px4.io (License: BSD 3-clause, LICENSE)
- Supported airframes (portfolio):
- Multicopters
- Fixed wing
- VTOL
- many more experimental types (Rovers, Blimps, Boats, Submarines, etc)
- Releases: Downloads
PX4 Users
The PX4 User Guide explains how to assemble supported vehicles and fly drones with PX4. See the forum and chat if you need help!
PX4 Developers
This Developer Guide is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
Developers should read the Guide for Contributions. See the forum and chat if you need help!
Weekly Dev Call
The PX4 Dev Team syncs up on a weekly dev call.
Note
The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the Dronecode calendar.
