Replication & Code

Equispaced RGT Formation Flying & Event-Driven Control Simulator

Role: Algorithm Developer & Numerical Implementation

High-fidelity numerical implementation and verification of an autonomous formation-keeping framework for equispaced satellites in Repeat Ground Track (RGT) LEO orbits under zonal geopotential perturbations (EGM2008).

Key Technical Highlights:

▸ Developed a custom MATLAB parser to extract and de-normalize zonal harmonics (J2–J10) from raw ICGEM gravity data files.
▸ Implemented an iterative root-finding algorithm to compute nominal semi-major axis offsets (Δa) via averaging theory, eliminating differential secular drift.
▸ Architected an event-driven state machine integrated with MATLAB high-order solvers (ode78/ode113) utilizing smooth zero-crossing trigger logic for impulse ΔV scheduling (GVE-based).
▸ Simulated a comprehensive 60-day mission life cycle analyzing threshold breaches, local relative geometry stability, and along-track / cross-track velocity budgets.
