PROFILE
Karthik Karumanchi
Developed and enhanced CubeSat flight software for the cmu-argus-2/FSW-mainboard repository, focusing on attitude determination, control, and telemetry reliability. Over four months, delivered features such as comprehensive logging, sensor data validation, and robust state estimation using Kalman filters and quaternion mathematics. Improved embedded systems integration by refining device drivers, expanding data logging, and enabling remote diagnostics for motor drive and magnetorquer subsystems. Addressed bugs in covariance propagation and sensor handling, while maintaining code quality through refactoring, linting, and static analysis. Leveraged Python and YAML to automate testing, streamline CI/CD workflows, and ensure maintainable, observable, and reliable flight software.

Apr 1, 2025April 2025 — cmu-argus-2/FSW-mainboard: Delivered enhancements to sensing, data logging, and diagnostics for motor drive and magnetorquer subsystems. Key changes include fixing DRV8235 current/voltage sensing issues and adding cubesat-access methods to retrieve driver current/voltage. Expanded data logging and retrieval for magnetorquer readings to improve diagnostics and monitoring. These efforts improve telemetry reliability, enable proactive maintenance, and reduce mission risk by providing precise telemetry and fault detection. Technologies demonstrated include DRV8235 torque control, enhanced sensing front-end, data logging, cubesat interface development, and telemetry instrumentation.
