We present four integration methods which exploit efficient numerical techniques for orbit propagation. The methods have been selected to compare the strategy of using first order differential equations, required by the use of regularization, to integrating the equations of motion directly so that second order integrators can be used.
All the methods have demonstrated high levels of orbital accuracy as well as very short integration times in astronomical simulations of long term dynamical evolution. We outline the bases of these techniques and illustrate their accuracy by comparing the orbital predictions with data from a GPS receiver on board a satellite in Sun synchronous LEO orbit.
