Telephone at the base of the satellite
It is believed that space technology is expensive and very difficult.
It turns out that a satellite can be built for less than $ 1000.
Matthew Reyes, Chris Boshuizen and Will Marshall launched the SmallSat satellite, which uses the Nexus One and Arduino as sensors and on-board computer.
The satellite was launched using a two-stage rocket Intimidator-5 by James Dougherty.
Used for managing SL4A - Scripting Layer for Android.
The second phone was used as a black box on the rocket. He used his GPS and accelerometers, as well as a camera, to record the launch from the rocket:
The first experiments were not entirely successful and the phone crashed on landing, only the memory card remained alive. But this made it possible to obtain valuable information about the flight. The next option was equipped with a parachute and the flight was successful - the phone flew to a height of 28,000 feet (8530 meters), recorded video and flight data and landed safe and sound:
')
The evolution of the phones made accelerometers, gyroscopes, camera, GPS, radio module in a tiny case available, and the processor power allowed replacing a bunch of expensive electronics with a regular communicator. The phone has everything you need to control the satellite and conduct research in microgravity.
Matthew talks about the evolution of SmallSat:
Do you remember the ironic statement that you have a computer in your pocket that is many times more powerful than the onboard computer that controlled the Gagarin missile? It is good to know that it is suitable not only for launching birds into pigs, but is quite capable of controlling a satellite.
