Feb 1, 2026February 2026 monthly summary for tiiuae/px4-firmware: Implemented a GPS data path hardening by increasing the LPUART TX buffer size for GPS ports. This change improves data transmission reliability and throughput for GPS streams, reducing backpressure during high-rate data loads. Submodules were updated to enable CONFIG_LPUART1_TXBUFSIZE=1500 and CONFIG_LPUART2_TXBUFSIZE=1500 for GPS1 and GPS2, with traceability to SSRCDP-12099.

Oct 1, 2025Month 2025-10: Focused on improving altitude estimation reliability in the PX4 firmware. Implemented a targeted bug fix by disabling GPS height data fusion in two airframe configuration files, preventing GPS height data from skewing the EKF2 altitude estimate. Commit 3ac9d4e0e6201f62a56f1c0be31bcf45edd27900. This change reduces altitude estimation inaccuracies, enhancing flight safety and mission reliability.

Sep 1, 2024In September 2024, delivered a robustness improvement to the DDS data path in tiiuae/px4-firmware by validating DDS Data Writer/Data Reader creation return values. On creation failure, the data writer is marked invalid to prevent cascading errors, reducing runtime instability and ensuring safer data handling in the DDS client. This change reinforces resilience of the communications layer, minimizes cascading failure risks, and supports more maintainable code paths for future enhancements.
