ABSTRACT:
In the present invention four thrusters are provided as a group of thrusters for collision avoidance. These thrusters contain a component of translational thrust for collision avoidance injection in their respective outputs, and are capable of simultaneously generating posture control torque around two coordinate axes, which are orthogonal to a thrust axis, in order to maintain the directional stability of the thrust axis during the injection. When abnormality arises in a group of thrusters for ordinary use, collision avoidance is executed by replacing all the thrusters for ordinary use by these thrusters for collision avoidance.
