Linux.conf.au 2014 – Day 5 – Keynote – Jonathan Oxer

  • How many people have wanted to work on something that went into space? – Everybody
  • How many people have actually done that? – about a dozen
  • How about if every kid could answer “tes” to that question
  • Cubesats – Small standard way to luanch tidy stats – 10cm cubes
  • ArduSat – Kickstart – June 2012
  • Feb 2013 – Revises design of board
  • Mar 2013 – New design built
  • June 2013 – Hardware integrated and built – ArduSat-1 and ArduSat-X
  • 3 Cubesats Launched to ISS include the 2 ArduSat’s
  • Need to upgrade/update Experiments in flight
    • Browser based updates
    • Code sent via Internet to california, run on duplicate of satellite
    • Transmitted to satellite
    • Distributed to one of the nodes
  • CubeSat System bus
    • Supervisor node controls smaller nodes
    • Stores stuff on Sd card
    • Allocates experiment to node, powers up the node
    • sends it via “serial port” to node
    • Supervisor controls Power and reset and serial for each node
    • node thinks it is just a stand-alone off the shelf Ardino
  • Satellite
    • 4-6 month life
    • 12-15 experiments
    • If allocated in 1 week blocks we can sell those for $300 each
    • So much backlog and interest is plan to launch 30 ArduSats/year for next 5 years
  • Make Satellite available
    • Flyable version costs approx $50k
    • Replace flying modules with open-source parts
  • TODO
    • Release of designs without attracting the lack helicopters
    • Flight computer design
    • Terrestrial sensor suite design
    • Development of education material
  • Wait there is more…
  • Water powered cube-sat
    • 5kg total mass, 2.5kg of water propellant
    • On kickstarter
