Abstract: To solve the problem of combined ignition of solid propellant micro-thruster array for orbit control, the layout of micro-thruster array was further optimized to enhance its applicability, and the distribution rule of thruster array was obtained. Combined ignition algorithm with thruster array was proposed. The mathematical model was established and the algorithm was verified. The simulation results show that the requirements of micro-satellite orbit control can be satisfied by the optimal design of thruster array. The mathematic model can solve the ignition problem, and ignition thruster can be addressed quickly by the proposed algorithm.
