The Effects of the IERS Conventions (2010) on High Precision Orbit Propagation [PDF]
Journal of Astronomy and Space Sciences, 2014 The Earth is not perfectly spherical and its rotational axis is not fixed in space, and these geophysical and kinematic irregularities work as dominant perturbations in satellite orbit propagation.

AEJ - Alexandria Engineering Journal, 2021 Fast and precise propagation of satellite orbits is required for mission design, orbit determination and payload data analysis. We present a method to improve the computational performance of numerical propagators and simultaneously maintain the accuracy level required by any particular application.

Estimation of the SGP4 Drag Term from Two Osculating Orbit States [PDF]
Journal of Astronomy and Space Sciences, 2003 A method for estimating the NORAD SGP4 atmospheric drag term from minimum osculating orbit states, i.e., two osculating orbits, is developed. The first osculating orbit state is converted into the NORAD TLE-type mean orbit state by iterative procedure ...
