Systems and methods for pointing a high gain antenna or other directional instrument connected to a platform by a gimbal are provided. A control system as disclosed can include a flight computer having a processor for executing software and a motor control board having a controller for implementing at least portions of a control algorithm. The software executed by the processor generates pointing commands and implements a Kalman filter included in a feedback loop in the form of a linear Kalman filter disturbance estimator of the control algorithm implemented by the controller. The control algorithm can further implement a proportional control position loop and a proportional control rate loop. Each axis of the gimbal is provided with an instance of the control algorithm and the Kalman filter. Moreover, the processor can be operated at a rate that is less than a rate at which the controller is operated.
