The threat of on-orbit collisions endangerssatellites, spacecrafts and astronauts themselves especially in low-earth orbits(LEO). Many collisions occurred between satellites and debris that include natural,operational and non-operational objects in space. The collision between Russiancosmos 2251 and American iridium 33, for instance, imposed the need for anaccurate orbital propagation module. In order to perform successful collisionavoidance maneuvers, the mission operators need the orbit prediction to be highlyaccurate. Simple impractical number of collision avoidance maneuvers representsdreadful solution to escape of collision. Fake warning means waste of fuel andresources of satellite. This paper introduces an enhanced model to increase theaccuracy of propagation estimation based on a precise perturbation model.}, keywords = {Orbit,propagation,Drag,TLE,Cowell,STK,SGP4,hpop,eclipse,ephemerides}, url = {https://amme.journals.ekb.eg/article_34732.html}, eprint = {https://amme.journals.ekb.eg/article_34732_a8d813b06e1944103f5e9b127c9f2d27.pdf} }
