Session 2 2 dr craig benson unsw canberra

  1. 1. The Buccaneer and Biarri Cubesat Missions Dr Craig Benson UNSW Canberra Buccaneer and Biarri missions in conjunction with DST Group All comments are mine and do not represent DST Group
  2. 2. Cubesats and their ilk • Cubesats, and other small satellites represent an opportunity for highly capable satellites to be launched with relatively low budgets and on short timelines • As an outsider, the current cubesat architecture is outdated and wasteful. They could be lighter, more capable, more flexible and faster to launch
  3. 3. Planet Labs Image: Planet Labs
  4. 4. Planet Labs 92 imaging satellites in orbit Rapid revisit 3-5m resolution imagery Failures and attrition Image: Planet Labs
  5. 5. Internet of Things • Globalstar already offer simplex STX-3 modules for low cost global tracking and monitoring of assets (via large LEO satellites)
  6. 6. ADS-B and AIS tracking • Monitoring of aircraft and ship beacons is a demonstrated capability with single PC-104 cards in cubesats Images: GOM Space Images: GOM Space
  7. 7. GNSS Occultations for Ionosphere monitoring GNSS Reflectrometry for ocean monitoring (esa.int)
  8. 8. Cubesat Launchers • Traditionally, small-size satellites fly as secondary payloads on major launches – Launcher issues: • Long lead time for integration • Qualification to minimise risk to main payload • Limited ability to influence orbit – Not responsive
  9. 9. Rocket Lab • 150kg to 500km sun-synchronous orbit • $5m/launch = $33k/kg Image: Rocket Lab
  10. 10. Virgin Galactic • 747 air launch • LOX/RP-1 2-stage rocket Image: Virgin Galactic
  11. 11. DARPA SALVO/ALASA • Twin programs for air launched light satellite to LEO – nominal 100lb for $1m • ALASA canceled due to propellant instability DARPA Artist Impression
  12. 12. Innovation • Most innovations will fail • Most companies will fail to make money • But launches will get: – Cheaper – More flexible – More responsive – Less risk averse • Responsive and affordable space access fits with modern innovation • Space is about services to Planet Earth
  13. 13. UNCLASSIFIED Project Biarri Namuru GPS Laser Tracker Launch: • Risk mitigation: July 2016 October 2016 • Main mission: 2017 – 2018 Formation Flying
  14. 14. Project Buccaneer UNCLASSIFIED Launch:- • Risk Mitigation: January 2017 • Main mission: 2018 Calibration measurements for JORN
  15. 15. Australian Involvement in Space • Components for space assets are a global market, with niche suppliers • Innovation is about using space to provide services to customers, not only telecoms and TV – Many new ventures will fly satellites, downlink data, and supply the data to users (Planet Labs) • Australia has a large area where LEO satellites can contain emissions solely with our territory – Can we offer expedited approval or special radio downlink capabilities?
