Nov 1, 2025Month 2025-11 — PX4/PX4-Autopilot focused on time synchronization improvements, featuring the inclusion of component and system IDs in MavlinkTimeSync to improve accuracy and reliability across autopilot components. Implemented and merged the change (commit 25138d0a124b199ea5fd82bfd38752807b6c593a) with co-authors Henry Kotze and Beniamino Pozzan (PR #25949). No major bugs fixed in this period for this repository; ongoing maintenance and alignment with time synchronization protocol were performed. Demonstrated end-to-end ownership from design to validation, with strong collaboration and knowledge of Mavlink protocol, embedded C/C++, and PX4 architecture.

Oct 1, 2025Month 2025-10 highlights: Delivered a critical bug fix in the EKF2 module of PX4-PX4-Autopilot to improve External Vision velocity (ev vel) timestamp handling. The patch makes the ev vel update use the measurement timestamp instead of the estimator’s own timestamp, resolving logging gaps when the timestamp sample is zero and improving data integrity for ev velocity measurements. This change strengthens the reliability of external vision data used for state estimation and flight control. Key commit: 7418d8400173412ae1356f28871027abddd0fdd8 (ekf2: ev vel, use measurement timestamp to update aid_src timestamp_sample; co-authored-by: henrykotze).

Sep 1, 2025September 2025 performance summary for PX4/PX4-Autopilot: delivered a stability-critical PWM fix on ESP32, correcting overflow when changing duty cycle after power-up and ensuring proper reload value calculations and register updates for reliable PWM output. The work improves motor control reliability and PWM signal integrity in flight-critical subsystems. Also refined code quality with cleanup and cherry-pick hygiene.
