Regularized analytical orbit theory with solar radiation pressure

A new non-averaged non-singular solution is derived for describing the orbital motion around the Earth under the influence of solar radiation pressure (SRP), using Kustaanheimo-Stiefel (KS) regularization technique. Despite the increase in the dimensionality of the system, there exists a symmetry in the KS space. Just three out of the ten equations are solved completely, while only initial conditions are changed for the rest, to produce the dynamics. Performance evaluation of the theoretical solution is carried out with the KS numerical orbit propagator under the assumption of a cannon-ball SRP model for the object. Different high area-to-mass ratio objects from high altitude orbits are considered for analysing the accuracy of the solution.
