WebIn celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space … Weban orbit at i = 65oand a nodal period of 89.65 min, which corresponds to an average altitude of 255 km. This turns out to be an orbit with the parameters (N,M,Q)=(16, -1, 7) which corresponds to a ground track that repeats every 111 orbits, i.e. weekly. the graph below shows how Kosmos-1249,
WebConvert the orbital velocity to angular velocity, and then multiply by the Earth's radius. Last, subtract the Earth's movement from this. v g n d = G M r 1 r R e − 0.465 k m s = ( 7.9 k m s) ( R e r) 3 / 2 − 0.465 k m s You can simply plot this. For length units, I'm using multiples of Earth's radius. So r=1 here is the surface.
