To overcome the stringent constraints of on-board resources and improve the fault detection capabilities of formation flying satellites,a Riemann distance-based fault detection data selection method applicable to the attitude control system of formation flying satellites is proposed.The Riemann distance measures the difference between the system's measurement information under fault-free and fault conditions.This is used to establish an evaluation index,which assesses the fault detection capability of the formation flying satellite attitude control system.On this basis,a fault detection data selection method is proposed,providing a theoretical foundation for the optimization of the system output information structure.The simulation has shown that the proposed method can effectively enhance the fault detection capability of the formation flying satellite attitude control system under the condition of limited on-board resources.
