PROFILE
Chunho Li
Licheng Li developed and enhanced attitude determination and control software for the Space-and-Satellite-Systems-UC-Davis/ADCS-Software repository, focusing on robust detumbling algorithms and sensor integration. Over seven months, Li refactored core C modules to derive angular velocity from magnetic field data, reducing external dependencies and improving testability. He introduced modular control logic, improved sensor calibration routines, and stabilized the build system using Makefile automation. Li’s work addressed both feature development and bug fixes, emphasizing maintainability, error handling, and simulation accuracy. By integrating algorithm optimization and embedded systems expertise, he delivered a more reliable, maintainable ADCS stack for satellite mission readiness.

Oct 1, 2025October 2025 (2025-10) monthly summary: Delivered the ADCS Experimental Framework Enhancements that integrate determination_experiment and ramp_experiment into ADCS.C, introduced the ADCS_HDD_TESTING mode for isolated hardware validation, and refined error handling for detumble and PID experiments. This work, combined with refactoring ADCS.C to call modular functions, improves testability, reduces integration risk, and accelerates experimental cycles. The commit bceb772be200568efbcc2cc729cca5600ea269d2 documents the function-call refactor.

Jan 1, 2025January 2025 Monthly Summary — Space-and-Satellite-Systems-UC-Davis/ADCS-Software Focused on strengthening the detumbling capability by deriving angular velocity from magnetic field readings rather than relying on a direct get_angvel call. This update makes detumbling more self-contained, robust, and testable, with internal data derivation and added helper functions for angular velocity calculation and threshold checks.
