PROFILE
Karthik Karumanchi
Karthik Karuman built and enhanced flight software for the cmu-argus-2/FSW-mainboard repository, focusing on attitude determination, control, and hardware integration for CubeSat systems. Over four months, he delivered features and bug fixes that improved sensor data validation, telemetry reliability, and diagnostics, using Python and embedded systems techniques. His work included refining Kalman filter logic for robust attitude estimation, expanding data logging for motor and magnetorquer subsystems, and automating hardware testing with scripting. By addressing code quality through refactoring, linting, and static analysis, Karthik ensured maintainable, testable code that supports reliable spacecraft operations and proactive fault detection in flight.
