TechEdSat to use ‘SatPhone’



TechEdSat will be deployed from the International Space Station (ISS). It is a 1U CubeSat that will demonstrate Plug and Play power architecture and two way communication via the satellite phone/data networks Iridium and Orbcomm.

UPDATE: The plan to transmit from space using frequencies allocated to Iridium and Orbcomm SatPhone ground stations has been canceled. A statement from the team says: “We were forced to disable the Iridium modem as our FCC license did not come in time. As usual, building the satellite is the easy part.”

There will be a 437.465 MHz beacon transmitting 1 watt to 1/4 wave monopole. Commanding is via the commercial networks and there is a 2 week watchdog timer to stop the beacon in the event of no commands being received.

TechEdSat will be launched along with Raiko, FITSat-1, We-Wish and F-1 to the ISS aboard HTV-3, currently planned to launch July 18, 2012. From there, it will be deployed into Low Earth Orbit  using the JAXA J-SSOD deployer, from the Japanese Experiment Module (JEM also known as Kibo).
