Considering the urgent need of rapid trajectory generation of boost-glide missile in mobile condition, seven key parameters of control variables were selected as the firing data, and the corresponding iterative calculation algorithms were proposed. The full-range trajectory was divided into the boost phase, initial phase, glide phase and dive attack phase, all these flight phases were described in a unified dynamics model. Firing data in different phases were calculated rapidly one by one, and multiple constraints were satisfied strictly, with the help of the parameterized iterative algorithm. Furthermore, a partly recalculation mode which uses the firing data of the center trajectory in the boost phase and recalculates the others was proposed on the basis of the full mode. The simulation results indicate that this method can achieve a great performance in the quick attack to a ground stationary target in mobile condition.
