Micro-thrust high-precision satellite formation system based on Cartwheel configuration

Micro-thrust satellite formation can better complete the high-precision aerospace satellite formation tasks. Close-range cooperative work is the basic feature of satellite formation flight, and the specific geometric configuration and relative movement between the satellites is the basic condition of the cooperative formation. But perturbation and other interference factors lead to the uncertain change of the relative relationship. It is necessary to design the formation configuration and information topology to achieve long-term high-precision formation maintenance. How-ever, the micro-thruster's mechanism requires a higher reliability and fastness of the satellite formation system. To this end, a micro-thrust satellite formation system based on Cartwheel configuration is proposed, and a topological network structure is designed to meet the system performance requirements. An online trajectory optimization algorithm based on particle swarm optimization (PSO) algorithm was designed. The application to the control system of satellite formation maintenance achieves a high-precision fast and stable control with low energy consumption.
