This paper investigates the finite-time relative position coordinated control problem of distributed spacecraft formation without velocity information over limited communication bandwidth. In this design, a dynamic event triggered transmission scheme among spacecraft is designed to reduce communication burden, and a finite-time extended state observer is proposed to estimate the velocity information and the effects of non-linearity and disturbance of each spacecraft. A fast terminal sliding mode control law is developed to achieve finite-time coordination of the overall spacecraft formation. Finally, a numerical simulation is presented to demonstrate the effectiveness of the proposed control strategy.
