Abstract Distributed remote sensing has attracted much attention for space exploration. The sensing ability is based on the system properties of the spacecraft cluster composed by multiple nano/micro spacecraft. In addition, the multiple nano/micro spacecraft formation can be rearranged for different applications. However, since the micro/nano spacecraft have little fuel, methods are urgently needed to maintain the stability of the distributed remote sensing nano/micro spacecraft formation for a relatively long period in a natural formation.The natural nano/micro spacecraft cluster formation is analyzed have for a multiple distributed remote sensing task scenario that optimizes the fuel usage and calculational efficiency. A direct parameter method was designed for the typical tasks of in-plane flying with a tree communication topology and leader-following topology modes. The orbit parameters of the followers are obtained directly by this method. STK simulations show this approach is accurate, robust, and useful for emergency remote sensing tasks.
