ORBIT-Lab

Main project · 2026-present · Aerospace / Embedded Systems / Applied Mathematics

ORBIT-Lab is a low-cost, precise hardware-in-the-loop platform for testing the attitude-control systems of 1U CubeSats. Its purpose is to reproduce, at an educational and experimental scale, validation workflows that normally require expensive aerospace equipment.

The platform combines:

mathematical and physical modeling;
reaction-wheel attitude control and sensors;
simulation and hardware-in-the-loop validation;
a custom onboard-computer software stack;
commercial components and accessible fabrication.

Current state: parts of the test CubeSat structure have been machined, frequency-calculation software is in development, and early work has started on the onboard-computer kernel.

Braess Paradox Computational Research

High school thesis · 2026 · Graph Theory / Optimization

A traffic-assignment study investigating possible instances of Braess' paradox in São José dos Campos. The model uses a real road network with Dijkstra shortest paths, BPR travel costs, Frank-Wolfe optimization, OSMnx, and NetworkX.
