The method of a low-cost verifiable in-orbit laser ablation experiment was given in this paper. With this method, a meteorite ball which was be releasing actively was ablated by multi-pulse continuous laser beams which were generated by a mall pulse laser with low energy. Through a combination of laser rangefinder, micro-propulsion module, and attitude control system, as well as acceleration curve measurement and integration, effective tracking and convenient measurement of velocity increment of the target meteorite ball have been achieved. Finally, specific design with specific experimental scenarios was provided, and preliminary simulation of the test effect was given. This work will provide a experimental idea for the impulse coupling coefficient in-orbit measurement which is the key parameter to evaluate the effect of laser ablation for asteroid orbit deflection with the real scene of asteroid defense.
