The concept of time-sequenced on-orbit separation for series-parallel multi-satellite assemblies is proposed. A separation spring assembly is designed under the premise of fully utilizing the launch vehicle fairing envelope. The separation velocity is derived through dynamic formula calculations, and the separation spring assembly is optimized based on the synchronization requirements of separation velocities. A rigid-flexible coupling dynamic analysis is conducted for the separation process of series-parallel satellites under different separation timing sequences, revealing the relative motion states of sub-satellites and upper stages during separation. Additionally, the collision probability at different stages is analyzed.
