Why are Keplerian elements used in TLEs instead of Cartesian state …

WebFeb 1, 2024 · If you just need to look for changes in the orbit state, you should use SGP4 to convert into position and velocity, propagate the state with and without the maneuver using something other than SGP4, and convert each of those to some orbital elements that aren't the excessively complicated mean elements used for TLEs. WebIn astrodynamics and celestial dynamics, the orbital state vectors (sometimes state vectors) of an orbit are Cartesian vectors of position and velocity that together with their time () … WebApr 24, 2024 · 1 The general solution to making n-vectors work using algorithms designed for (n+1) dimensions is to set the position of the unused elements to 1, not 0.
