3.  Calculates the tracks of earth orbiting satellites.  Calculations are based on the SGP4/SDP4 model, highly accurate.  Simplified General Perturbations Satellite Orbit Model 4 (NASA/NORAD)

5.  Developed by Cal Poly and Stanford University  10cm 3 and has a mass of 1kg  Powered by photovoltaic cells and rechargeable batteries  Usually launched piggyback to commercial satellites  Costs $30,000 to $50,000 to build and the same amount to ride piggybacked on a commercial satellite.

6.  Track a low orbit satellite from horizon to horizon  Move a 3 meter satellite dish  Interface to SatPC32

7.  Gears and motor  Motor controllers to interface with SatPC32  Digital Encoders to control position of the dish  Use/Modify existing designs for elevation and azimuth control

9. COMING SOON  Force due to wind  Inertial Force  Gear calculations
