I’m Siavash Sabzy. I explore orbital dynamics, spacecraft navigation, and mission design through computation.
A computational approach to understanding how spacecraft move, navigate, and work together.
My interests sit at the intersection of astrodynamics and space systems—from the structure of multi-body trajectories to the practical challenges of satellite navigation.
I use code to explore these problems: building numerical tools, studying orbital configurations, and turning mathematical models into results that can be examined and shared.
This site brings together a few projects from my public work. Each one is a small window into the questions I enjoy working on.
