2. Problem Statement To build an altitude and azimuth steerable satellite dish, with a receiver or a transceiver for communication.

3. Solution Take an existing 3 meter satellite dish Add on a Azimuth Motor and gear system Add on position control sensors Take an existing satellite modeling program and utilize it for location control Design motor controls for both Azimuth and Altitude motors

5. Worm Gear 20 inch diameter able to hold post 90 tooth assists in position count. Will require a roller- thrust bearing for reduced friction loss.

6. Power required Total weight of 623 lbs EF of 2.5 Working weight of 1557.5 lbs Rgear = 21 in, RPM of dish = ½ Torque = WxR= 1557.5 x 21 in = 32707.5lbin HP = TxRPM/63025 = 32707.5x.5/63025 =.259 hp
