Hey everyone: I have the following problem: as the title suggests I need to be able to move my satellite receiver to any geostationary satellite orbiting. I want to use a unipolar stepper motor and either half step, or I might Microstep the motor to get more accuracy. I am looking to operate it at very low speeds. The motor will be oriented horizontally, and a worm gear or any other type of gear will be used to get the 360' motion. What I would like to know what rated motor should I get that can handle the satellite load of about 5-8kg??? The attached file is a basic diagram of the orientation of the motor.
