PhoneSat

PhoneSat was a NASA project that demonstrated the use of commercially available smartphones as the primary avionics and processing systems for nanosatellites, specifically CubeSats. The project aimed to significantly reduce the cost, complexity, and development time associated with building and launching satellites.

The core concept involved utilizing the processing power, sensors (such as accelerometers and magnetometers), cameras, and communication capabilities of existing smartphones. These smartphones were integrated with a basic satellite structure, power system, and radio communication system to create a functional spacecraft.

The primary objective of the PhoneSat missions was to prove the viability of using off-the-shelf consumer electronics in space and to collect data on the performance of these components in the harsh environment of orbit. This included monitoring the smartphone's performance, capturing images of Earth, and transmitting data back to ground stations.

The project consisted of several iterations, including PhoneSat 1.0 and PhoneSat 2.0. PhoneSat 1.0 utilized Nexus One smartphones running the Android operating system, while PhoneSat 2.0 employed Nexus S phones and incorporated additional features like solar panels for extended mission duration and attitude control using reaction wheels.

PhoneSat was considered a successful demonstration of rapid satellite development and low-cost space exploration, paving the way for future missions utilizing similar commercially available technologies. The project helped to democratize access to space by reducing the barrier to entry for smaller organizations and educational institutions interested in building and launching satellites.
