Appl. Math. 80(2):554–568, 2015), determined that the Simplified General Perturbations 4 (SGP4) expression for the rate of change of the mean anomaly M is missing a secular term of order J 2. It was also speculated that the adverse effects of this missing term on propagated satellite …

Webbhe Simplified General Perturbations (SGP) model series began development in the 1960s (Lane 1965), and became operational in the early 1970s (Lane and Cranford, 1969). The development culminated in Simplified General Perturbations-4 (SGP4), and although the name is similar, the mathematical technique is very different Webb21 okt. 2024 · Simplified perturbations models are a set of five mathematical models (SGP, SGP4, SDP4, SGP8 and SDP8) used to calculate orbital state vectors of satellites …
Webb6 apr. 2024 · This is what SGP4 --- the (U.S. Air Force) Simplified General Perturbations Theory, version 4 --- really does. It is not "propagated linearly with no timesteps", it is implemented as a sequence of nested polynomials and trig functions into which one simply plugs the end time, and the final result is calculated from it in one step.
