Work Experience

GNC Algorithms Engineer, ELSA-M Project at Astroscale UK Ltd.

October 1, 2022 - October 1, 2025

Delivered pre-flight-validated attitude guidance and control algorithms for on-orbit servicing missions. Integrated barrier-based constraint handling into an existing Lyapunov-stable attitude controller to enable real-time sun-pointing while respecting exclusion zones and rate limits. Implemented SDRE-based retreat and proximity maneuvers. Built high-fidelity 6DoF simulations for ACS validation (Sun, LVLH, ECI modes). Reduced tumble rates by ~45% through improved attitude maneuver planning. Mentored junior engineers and reviewed flight-critical control logic. Tools: MATLAB/Simulink, C++, Git, custom simulation frameworks.

Specialist GNC Engineer - Launch Vehicle Development Department at ROKETSAN Inc.

March 1, 2019 - September 1, 2022

Defined delta‑V budgets and preliminary GNC architecture for an orbital transfer vehicle adopted at Phase‑A review. Built EKF & SR-UKF filters with bias/noise models, achieving 3‑σ position error at apogee. Implemented 6DoF orbit propagator incl. J2, third-body & nongravitational forces via Gauss’ variational equations. Designed PWPF-based attitude controller for an exoatmospheric 6DoF thruster system meeting the pointing requirement. Developed fuel-optimal ascent/coast guidance (Pontryagin’s minimum principle) saving propellant.

Control Engineer - Advanced Control Technologies Department at ROKETSAN Inc.

April 1, 2017 - February 1, 2019

Designed cascaded BLDC position-velocity controller incl. FOC for BLDC-driven aerodynamic surfaces; validated on HIL. Crafted quadratic & frequency-domain controllers for thrust-vector control (TVC). Deployed BLDC algorithms (motor-control firmware) to dsPIC, enabling >20 kHz ISR loop.
