Worked on the ArduPilot/ardupilot repository to enhance the reliability of flight control systems by implementing a Compass Calibration Reboot Guard. This update modified the calibration logic so that the system only reboots after successful MAG_CAL calibration across all compass instances, preventing unnecessary reboots when calibration fails. The approach improved system stability and reduced downtime during mission-critical operations, directly benefiting user experience by minimizing disruptions. The work involved C++ programming and algorithm design within embedded systems, focusing on robust error handling and state management. This contribution addressed a key bug, emphasizing careful integration and attention to operational reliability in embedded flight software.
