The invention discloses a spacecraft approaching maneuver tracking control method based on observation and collision avoidance constraints, and the method comprises the steps: employing dual quaternion description to establish a relative kinematics and dynamics model, employing a relative pose dual quaternion to construct an observation sight line constraint and a collision avoidance safety constraint, designing an artificial potential function based on the two constraints, and carrying out the calculation of the artificial potential function. A near maneuver tracking control law is further designed, and the provided near maneuver tracking control method can enable the service spacecraft to approach the target spacecraft under the condition that observation and safety constraints are met all the time and finally keep stable tracking of the target spacecraft.
