Contributed to the Space-and-Satellite-Systems-UC-Davis/ADCS-Software repository by developing and enhancing embedded control features for satellite attitude determination and control. Leveraging C and C++, work included implementing new ADCS modes, robust error handling, and sensor calibration routines to improve reliability and testability. Delivered API extensions for virtual_intellisat, enabling eclipse detection and attitude status reporting, while refactoring sensor data paths for maintainability. Integrated retry logic for sensor reads and introduced type-safe status handling to reduce ambiguity. Focused on incremental, low-risk changes, the developer emphasized clear API contracts, disciplined version control, and thorough testing, resulting in safer, more autonomous satellite operations.

Jan 1, 2026January 2026 performance summary for Space-and-Satellite-Systems-UC-Davis/ADCS-Software focused on improving sensor status handling. Delivered a typing enhancement by introducing a SensorStatus enum to replace a plain int, plus an API refactor to return the status enum by reference for clearer semantics. These changes improve maintainability, reduce ambiguity in sensor status retrieval, and lay the groundwork for safer diagnostics and future feature work in sensor subsystems. No major bugs were fixed in this period based on the provided data.

Oct 1, 2025October 2025: Focused on robustness of ADCS sensor data paths. Delivered Magnetometer Data Acquisition Reliability Enhancement by adding retry logic for magnetometer reads and sensor calibration, allowing up to three attempts before signaling failure. This change reduces data gaps during transient communication errors and improves attitude determination reliability, contributing to safer, more autonomous satellite operation. The work is tracked under Space-and-Satellite-Systems-UC-Davis/ADCS-Software with a single commit documenting the retry mechanism.

May 1, 2025May 2025 monthly summary for Space-and-Satellite-Systems-UC-Davis/ADCS-Software. Delivered Rotisserie mode in the ADCS system with a PID experiment control loop, enabling controlled experiments and automated test runs. Extended the PID experiment function to accept target and infinite loop parameters for sustained operation. Introduced error status for Rotisserie mode and robust error handling for PID experiment failures, improving safety and reliability. No critical bugs fixed this month; however, the implemented error handling and mode management reduce failure modes and set the stage for repeatable testing. These changes enable faster iteration, better traceability, and stronger confidence in attitude control experiments.
