SGP4

The SGP4 model to calculate orbital state vectors of near-Earth satellites

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

SGP8

The SGP8 model to calculate orbital state vectors of near-Earth satellites

SGP is the first orbit propagator. It has been developed by Hilton and Kuhlman in 1966 thanks to one of Kozai's research work made in 1959. It is made for satellites orbiting near the Earth which
