A trio of PhoneSats is operating in orbit, and may prove to be the lowest-cost satellites ever flown in space. The goal of NASA's PhoneSat mission is to determine whether a consumer-grade off-the-shelf commercial smartphone can be used as the main flight avionics of a capable, yet very inexpensive, satellite.
NASA’s prototype smartphone satellite, known as PhoneSat 1.0, is built around the Nexus One smartphone made by HTC Corp., running Google’s Android operating system. The Nexus One acts as the spacecraft onboard computer. Sensors determine the orientation of the spacecraft while the smartphone's camera can be used for Earth observations. Commercial-off-the-shelf parts include a watchdog circuit that monitors the systems and reboots the phone if it stops sending radio signals.
NASA’s PhoneSat 1.0 satellite has a basic mission goal — to stay alive in space for a short period of time, sending back digital imagery of Earth and space via its camera, while also sending back information about the satellite’s health.
As part of their preparation for space, the smartphones were outfitted with a low-powered transmitter operating in the amateur radio band. They sent the image information to awaiting hams who worked with the Ames engineers to stitch together multiple, tiny images to restore the complete Earth view.
