A reaction compensated steerable platform device is disclosed. The reaction compensated steerable platform device can include a base, a steerable platform movably coupled to the base, and a reaction mass movably coupled to the base. The reaction compensated steerable platform device can also include a primary actuator coupled to the steerable platform and the base to cause movement of the steerable platform. The reaction compensated steerable platform device can further include a secondary actuator coupled to the reaction mass and the base to cause movement of the reaction mass. In addition, the reaction compensated steerable platform device can also include a load sensor configured to provide feedback for actuation of the secondary actuator, such that the reaction mass moves to compensate for a load induced on a support structure by the movement of the steerable platform.
