This submission is an interactive MATLAB script named npoe.m that can be used to propagate spacecraft in Earth orbits and model important orbital events. This script implements a special perturbation solution of orbital motion using a variable step size Runge-Kutta-Fehlberg (RKF78) integration method to numerically integrate Cowell’s form of the system of differential equations. Orbital events are predicted by embedding the RFK78 algorithm within Brent’s derivative-free methods for finding the single roots and extrema of nonlinear equations. The user can control both the integration and root-finding convergence criteria.
