Electric orbit raising with variable thrust

摘要: Systems and methods for launching a satellite into orbit that optimize the mass of delivered orbit. A carrying one or more chemical propulsion devices electric is launched transfer using launch vehicle. In embodiment, selected device fired to raise from an intermediate One final geosynchronous throttled produce variable thrust levels so as operate at all optimum specific impulse level another may deliver near-geosynchronous instead this case, place in its yet vehicle be used starting after which achieve raising step omitted.
