Worked on enhancing the documentation for compass calibration in the PX4/PX4-Autopilot repository, focusing on improving clarity and reducing user misconfiguration. The update clarified that compass priority is automatically set during calibration, with explicit guidance favoring external over internal compasses to minimize manual setup. Redundant notes regarding CAL_MAGx_PRIO were removed to streamline the documentation and better align with the calibration workflow. The work was implemented using Markdown and technical writing skills, leveraging AI-assisted drafting tools and incorporating human review. These changes aimed to improve maintainability, reduce support requests, and ensure the documentation accurately reflected the current calibration process.
