The invention discloses an intermittent pulse pseudo-continuous thrust deorbit mode in space tethered towing transfer, provides a safe, stable and efficient orbit transfer mode suitable for a tethered combination, and belongs to the technical field of satellite orbit transfer design. During working, a space tugboat and an abandoned satellite are connected through a tether, the space tugboat is provided with a tether winding and unwinding device, the tether is wound and unwound through the tether winding and unwinding device to keep continuous small tension of the tether, and the abandoned satellite is deorbited under the action of the tension of the tether. The space tugboat provides sequence pulse orbit control thrust, the orbit control thrust of the space tugboat is larger than tether tension, the space tugboat controls on-off of the orbit control thrust by judging the distance and the relative speed between the space tugboat and the abandoned satellite, and it is guaranteed that the relative distance between the space tugboat and the abandoned satellite changes in a set interval. The specific implementation process of the intermittent pulse pseudo-continuous thrust deorbit mode in the space tethered towing transfer comprises four stages: an acceleration far-away stage, a deceleration far-away stage, an acceleration approaching stage and a deceleration approaching stage.
