Arrowhead Systems have experimental time on Ardusat, with access to every sensor, from the Geiger counter to an open-source spectrometer (called Spectrino), strain gauges, magnetometers, vibration and shock sensors, gyroscopes and accelerometers, cameras and more.

Two ArduSats are planned to launch in 2013, it is understood both will be deployed from the ISS by the JEM Small Satellite Orbital Deployer (J-SSOD) of the Japan Aerospace Exploration Agency (JAXA).
ArduSat’s are open-source arduino-based nanosatellites developed by NanoSatisfi. They will have an extensive sensor-suite onboard and will allow users to upload their own code and run their own experiments.
ArduSat will use a GomSpace NanoCom U482C which is a half-duplex UHF transceiver operating in the 435-438 MHz band. It implements Forward Error Correction (FEC) and Viterbi coding based on the CCSDS standards in order to improve reliability and throughput of the space link.
NanoSatisfi was founded by Austrian-born Peter Platzer a former high-energy physicist (CERN), former Hedge Fund Quantitative Trader, avid HP-41 hacker and Arduino enthusiast, along with Belgian aerospace engineer Jeroen Cappaert KK6BLQ intern at NASA Ames Research Center, Canadian aerospace engineer Joel Spark KK6ANB intern at EADS Astrium and Hungarian Reka Kovacs intern at NASA Ames Research Center working on alternative methods of public outreach for space science. The four founders met at the International Space University in Strasbourg and thought that they could do something to provide affordable, open-source space exploration for everyone.
