  3. UND Vision 1. Moored Balloon 2. Free Balloon 4. AgCam (ISS) & CubeSat • AEROCam 2000 2000-2001 2001-2002 2002-beyond 10 October 2002

  4. What is a CubeSat Idea originated at Stanford University by Professor Robert Twiggs California Poly responsible for launch integration Size ~ 10 cm (4”) Cube Mass ~ 1 kg 10 October 2002

  5. Mission • Successfully build and launch a CubeSat • Transmit a single digital image from space and receive the image on Earth 10 October 2002

  6. Goal Orbit Earth for approximately 8 months Transmit numerous digital images to Earth Transmit health/status data to Earth Transmit data from a commercial/ government sponsored payload to Earth 10 October 2002

  7. Launch Expected early 2004 launch 800 kilometer orbit Approximately $80,000 Rent space for government/industry payload Alumni support: “Decameter for a Dollar” campaign 10 October 2002

  8. System Overview 10 October 2002

  10. DesignSpecs Requirements Mass not to exceed 2 kg Center of mass within 2 cm of the geometric center Structure Material: Aluminum 6061 Testing Vibration qualification test Thermal test Vibration acceptance test Integration 10 October 2002

  11. Mass Budget oz. gm. 10 October 2002

  12. Mass Budget 10 October 2002

  13. SizeBudget Total volume available = 10 *10*20 cm = 2000 cm^3 Total Volume Used = 680.3 cm^3 66% Volume Remaining Does not include wires and other misc. connections 10 October 2002

  14. P-Pod Aluminum 7075-T6 Spring Deployed Thermal line cutter actuator Railings Interface port (access CubeSat in deployer) 10 October 2002

  15. Testpod Internal dimensions same as launcher tube Will accommodate double and triple cubes Designed and manufactured at UND 10 October 2002

  16. Testpod Launch condition testing Needs two mounting plates Bolts to shaker table 10 October 2002

  19. Why Attitude Control? Alignment with the Earth’s magnetic field Picture footprint 10 October 2002

  20. Attitude Control Magnetic torque rods Uses magnetic torque to point satellite Gravity gradient Uses boom (weight) to align with Earth’s gravity gradient Magnetic alignment Makes use of a magnet to align with the Earth’s magnetic field Decreasing Complexity Active Passive 10 October 2002

  21. Active Control Relies on global position system data (GPS) Cannot obtain unlocked GPS module 10 October 2002

  22. Magnetic Alignment Extremely strong Rare-Earth magnets Larger magnets produce more torque Probability of “seeing” Earth increases from 95.88% to 99.25% at 800 km orbit 10 October 2002

  23. Magnetic Testing Helmholtz Coil • Constant magnetic field near center • Used to determine magnetic torque 10 October 2002

  24. SolarCells GaAs – Galium Arsenide Most common in space High efficiency 10 October 2002

  25. Solar Cell Circuitry • Used to control charging of system batteries • Constantly monitors output of solar cells 10 October 2002
