It allows computation of the position of a satellite in space at a given time through the use of Two-Line Element (TLE) sets and the SGP4 algorithm that has been implemented in Python from the original work of Vallado et al. Basically current_state = SGP4(old_state, time_since_old_state) Luckily, these functions were released together with a Fortran implementation, so porting it to whatever language you want is fairly straight forward. Python script to calclulate the ISS position/velocity with SGP4 algorithm. 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.
