A sattelite positioner counts pulses returned by the positioning system. For example, every time the motor makes 1 turn, 4pulses are returned, by counting these pulses the controller can calculate where it is in respect to it's previous position and/or a home position.

If you want a more accurate form of movement you could use a servo motor. These motors move in small steps, and every step is of fixed length. So one could move a certain lenght by making a certain amout of steps
