The 2012 Bay Area Maker Faire in San Mateo took place May 19-20 and among the stands was one displaying the PhoneSat amateur radio satellites.
There are two types of of these satellites both of which run the Android operating system and will be enclosed in a standard 1U CubeSat structure.
PhoneSat 1.0 cost about $3500 and is built around the Nexus One smartphone, it operates on battery power only with a mission lifetime of approx 1 week.
PhoneSat 2.0 is more expensive at $8000. It is built around the Nexus S smartphone and has solar panels on each face and a mission lifetime until de-orbit of approximately 2 weeks.
The IARU has coordinated a frequency of 437.425 MHz for the AX.25 AFSK downlink.
The first launch is scheduled for the third quarter of 2012 on Antares-110. It will carry two PhoneSat 1.0 satellites and one PhoneSat 2.0. A second PhoneSat launch is expected to occur in 2013.
