Model Satellite 2021
TEAM LEAD · AUTOGYRO DESCENT · 199-PAGE CDR
A rocket-deployed model satellite that slows its own fall: parachute to 400 m, then an autogyro rotor, a ten-second PID altitude hold at 200 m and a pyrotechnic smoke marker.

LIVE TRACE
A live trace of two systems I worked on: a CAN frame arriving over SLCAN is matched against a Vector DBC, decoded into pack voltage, current and state of charge, checked against the cell balance limit and drawn on four synchronised real-time charts; then a model-satellite telemetry packet comes down at 1 Hz, is CRC-checked, resolved into flight state, written to the database and mirrored to CSV, and drawn on the operator's map and attitude display.
I work on satellite and ground systems, embedded software and control — telemetry that has to arrive, buses that have to decode, and the software that has to stay honest about both.

FOUNDER & TEAM LEAD — TALIA AEROSPACE
TÜRKSAT Model Satellite
Four years leading the same team through Türkiye's model satellite competition. I owned the system architecture, the mission profile, the integration plan, the ground station and the actively controlled landing — and in 2022 the design met all 39 requirements and reached the national final again.

02GROUND SYSTEMS SOFTWARE
A screen the operator can fly a balloon from
R&D internship in TÜRKSAT's Satellite R&D Directorate, on the ground-station desktop software for a tethered aerostat system. The job was to watch the data coming down during flight, record it, and put it in front of the operations side in an order they could actually work from.

- Telemetry interface in Java Swing — altitude, position, environmental data and system health on one screen
- Data logging through JDBC / MySQL, so a flight can be read back afterwards
- Integration work with the hardware and systems teams

WHAT IT LEFT ME WITH
Working against a live data stream, and seeing at close range how ground-system software has to sit between the operations side and the hardware side — the same seam the model satellite ground station sits on, this time inside a real satellite organisation.

Printing in microgravity, without adding an actuator
Real-Time Active Vibration Compensation in Microgravity Additive Manufacturing via Kinematic Speed Modulation.On a station, the micro-vibration environment shows up directly in FDM surface quality. Instead of adding a counter-actuator, the approach modulates the print head's instantaneous kinematic speed in firmware so the motion never excites the structure's resonances in the first place.

WHY IT MATTERS ON ORBIT
Anything printed on a station is printed inside its vibration environment. Answering that in firmware rather than with another actuator means no added mass, no added power draw, and no new hardware to qualify — three arguments that decide things in space systems.

Effects of process parameters on surface roughness in fused deposition modelling after cusp filtering
ALI DEREYURT · EBUBEKIR KOÇ — IN PREPARATION
Layer height, wall count, infill density and print speed in a full factorial design: 324 surface profiles from 108 specimens, measured to ISO 4287/4288. To separate the dominant effect of layer geometry I developed a cusp filter locked to the measured peak and valley positions — after filtering, speed becomes significant at p = 0.005.
Multi-objective parameter optimisation in fused deposition modelling using machine learning and Bayesian optimisation
ALI DEREYURT · EBUBEKIR KOÇ — IN PREPARATION
End-to-end approach that reads an uploaded 3D model through four orthographic views and a vision-language model, predicts roughness with monotonicity-constrained gradient boosting (5-fold CV R² = 0.989 ± 0.007, LOOCV R² = 0.991, RMSE 0.569 µm) and balances roughness, material use, print time and strength through Bayesian search with slicer validation. Full cycle ≈ 270 s.
