  1. CAN WE TURN A PHONE IN TO A SATELLITE? Android Open 2011 San Francisco,10th Oct. 2011

  2. Why Phone Based Satellite? Status quo: • Typical satellite costs: $500m • ‘Low Cost’ satellites: $10m But… • All key capabilities of a satellite are in a phone • A cell phone based satellite costs ~$5k in parts • Launch for a 1U = $50-70k • With a 100x reduction in cost, could there be a vast array of new potential applications?
