Abstract In this paper, the relative position parameters of the target spacecraft are obtained by using the vision measurement and the target manoeuvre positions are calculated through the equidistant interpolation method. Furthermore, new switch control laws under constant thrust are designed for active collision avoidance manoeuvre of the chaser along a designated trajectory. The switch control laws are obtained based on the acceleration sequences and the working times of thrusters in three axes which can be, respectively, computed by the time series analysis method. The perturbations and fuel consumptions are addressed during the computation of the working times. The simulation results show that, with the switch control laws, the chaser will manoeuvre along the designated trajectory when there is a possibility of collision.

    Highlights ► The target manoeuvre positions are calculated through the equidistant interpolation method. ► The switch control laws are computed by the time series analysis method. ► The fuel consumptions are addressed during the computation of the working times.
