3  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.

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

5  Gears and motor  Motor controllers to interface with SatPC32  Sensor gears to control position of the dish  Use/Modify existing designs for elevation and azimuth control
