WebOrbital station-keeping. In astrodynamics, orbital station-keeping is keeping a spacecraft at a fixed distance from another spacecraft or celestial body. It requires a series of orbital maneuvers made with thruster burns to keep the active craft in the same orbit as its target. For many low Earth orbit satellites, the effects of non-Keplerian ... WebDec 13, 2001 · and multiplying both sides by r/m GM/r = v2. If T is the orbital period, since the distance covered by the Earth each orbit is 2πr, vT = 2π r Divide by T v = 2π r/T Square: v2 = 4π2r2/T2 and therefore GM/ r = 4π2r2/T2 Divide both sides by r2 : GM/ r3 = 4π2/T2. from which Kepler's 3rd law for circular orbits follows.
