A system and a method for commanding a spacecraft (2) to perform a three-axis maneuver purely based on "position" (i.e., attitude) measurements. Using an "inertial gimbal concept", a set of formulae are derived that can map a set of "inertial" motion to the spacecraft body frame based on position information so that the spacecraft can perform/follow according to the desired inertial position maneuvers commands. Also, the system and method disclosed herein employ an intrusion steering law to protect the spacecraft from acquisition failure when a long sensor intrusion occurs.
