Main Features and Improvements

With over 3000 commits a lot of the changes are not listed here. These changes represent the main improvements in the system.

Multicopter

• Limited-jerk trajectory generator for auto mode
• Smoothing of takeoff
• Mixer rewrite and Airmode for all axes
• Improved Acro performance (keep integrators always enabled in-air)
• Spool-up time for motors after arming
• Orbit flight mode
• Airspeed robustness (fault detection + failover) [BETA]

VTOL

• Improved support for tiltrotors
• Rate controller architecture change (run fixed wing & multicopter rate controller together to have dedicated rate controller for one set of actuators)
• Active weathervane based on direction of desired thrust vector
• Migration guide (vtol roll direction parameter - V19_VT_ROLLDIR)

PX4/ECL - Estimators improvement

• Reduced latency from receipt of IMU data to output of vehicle Pose data
• Multi GPS support (GPS blending and failover)
• Support for Fusion of GPS heading
• Miscellaneous optical flow data use improvements
• Miscellaneous VIO data use improvements
• Improve stability of attitude alignment and yaw reset at large tilt angles (eg tailsitters)

PX4/GPSDrivers

• Support for u-blox F9 generation (RTK)
• Initial support for Septentrio

Computer Vision & Autonomy

• Full bidirectional VIO uORB messaging, with linear/angular velocity and covariance propagation, besides pose data;
• Fast-RTPS bridge client and IDL definitions code generation improvements for a better integration with px4_ros_com (PX4 bridge with ROS2).

PX4/Avoidance

• Collision Prevention in Position Control
• Obstacle Avoidance in Mission Mode
• Pre-flight checks and failsafe mechanisms for Obstacle Avoidance in Mission mode

Simulation

• SITL lockstep (jMAVSim + Gazebo support)
• Faster or slower than real-time simulation, support to pause or step through code, enables SITL on older or slower hardware
• Simulation in Hardware module
• Avoidance in Gazebo
• Serial port configuration improvements

Logging improvements

• Mission log: Minimal summary log file for flight meta data

Onboard computer / middleware improvements

• Improved support for ROS2
• Initial support for monitoring of an onboard computer
• Bootloader update on v2 boards
