Research on Far-Field Safety Analysis and Design Method in Multi-satellite Launch Mission

To the issue of far-field safety of multi-body in multi-satellite launch mission with same rocket, this paper presents the influence relationship between different separation velocities and orbital parameters based on orbital dynamics, and presents the design requirements for separation velocities that meet far-field safety constraints. And then a prediction and review method of multi-body flight spacing is provided based on the worst-case force analysis model, then a complete set of far-field safety analysis and design method is proposed for multi-satellite launch mission. The implementation results of actual flight missions indicate that this method can effectively ensure the far-field safety of multi-body after satellite rocket separation, and is helpful in guiding the safety design of multi-body separation for multi-satellite launch mission with same rocket.
