During August 2025, Matas Razgunas focused on improving GPS altitude reporting in the peterbarker/ardupilot repository. He addressed a bug affecting SBF receiver data by correcting the handling of undulation, ensuring that altitude is reported as Above Mean Sea Level (AMSL) rather than ellipsoid height. This C++-based fix resolved discrepancies in flight data, enhancing the accuracy of mission planning and compliance with airspace requirements. By leveraging his expertise in embedded systems and GPS technology, Matas delivered a targeted solution that improved the reliability of mission logs. The depth of his work is evident in the precise, traceable code changes implemented.
