Analytic Orbit Propagation – Method of Markley and Jeletic

Fast analytic orbit propagator using the method of Markley and Jeletic.

This submission is a MATLAB script named demo_aorbit that demonstrates how to interact with a MATLAB implementation of the analytic orbit propagator described in “Fast Orbit Propagator for Graphical Display”, Journal of Guidance, Control and Dynamics, Vol. 14, No. 2, March-April 1991, by F. Landis Markley and James F. Jeletic.

The key features of this algorithm are;

1. J2 perturbation of the osculating semimajor axis only
2. angular orbital element osculating versus mean errors are of order J2
3. propagation of osculating orbital elements using a mean-to-osculating transformation
