The invention discloses a rocket upper stage optimal accessible orbit rapid planning calculation method. The method comprises the following steps: firstly, acquiring upper stage maneuvering-before initial state information; secondly, calculating the number of orbits of satellite injection after maneuvering of rocket upper stage through a simplified upper stage maneuvering model; then, calculatingtotal speed increment needed for capturing a satellite to a predetermined orbit; and finally, by an intelligent evolution algorithm, solving the upper stage optimal accessible orbit which minimizes the satellite capturing total speed increment. In the method provided by the invention, minimizing of the satellite capturing speed increment is taken as an optimization index, thus, introduction of weight selection is avoided, actual demands are met maximally, and the method has the advantages that the upper stage accessible orbit is optimal, calculation speed is high, and practicability is high. 本发明公开的一种火箭上面级最优可达轨道快速规划计算方
