The SGP4 model was developed by Ken Cranford in 1970.
WebbGeneral perturbations element sets generated by NORAD can be used to predict position and ve- locity of Earth-orbiting objects. To do this one must be careful to use a prediction method which is compatible with the way in which the elements were generated.
