WebbThe answer to both of these questions is perturbations. Contrary to how we would prefer orbital mechanics to work, true anomaly is not the only COE changing. To some degree, every COE we have discussed up this point changes. This chapter will discuss why these perturbations exist and how we track them. With that, let us look back at the big ...

Simplified perturbations models are a set of five mathematical models (SGP, SGP4, SDP4, SGP8 and SDP8) used to calculate orbital state vectors of satellites and space debris relative to the Earth-centered inertial coordinate system. This set of models is often referred to collectively as SGP4 due to the frequency of use of that model particularly with two-line element sets produced by NORAD and NASA.
