MECHANIC

A PD controller reads the chaser's (noisy) position and turns the error into a thrust vector — proportional gain pulls it toward the port, derivative gain damps closing velocity. A second PD loop keeps the nose pointed prograde. RCS thrust burns a limited fuel budget; run it dry before docking and the ship drifts uncontrolled.
