  1. Team Balloon Satellite II Multi-Disciplinary Senior Design CSEN 4201 Level II Mid-Term Report 17 October 2003 Mentor: Tony Kim

  2. Goals For Project • Develop a reusable balloon satellite • Real-Time Data Transmission • Re-launch with new payloads in one day  Obtain the greatest amount of communication bandwidth capable with existing technology and budget.

  3. Goals For Project (cont.)  Obtain scientific data in radiation, solar activity, and atmospheric science. • Senior engineering design class • Multi-disciplinary • Fulfill future ABET requirements for TAMUK • Fulfill Senior Design requirement

  4. Design Objective • Construct reusable satellite • Explore outer atmosphere • Return safely to Earth • Satellite shall withstand up to ten launches

  5. Design Objective (cont.) • Weight: no more than 12 pounds • Ascent Time: 90 – 100 minutes • Altitude: at least 100,000 feet • Descent Time: 30 minutes via parachute

  6. Work Breakdown Structure

  7. Breakdown Structure Detail • Communications • Packet Radio • Transmission • Ham Radio Licenses • Video • Antennae • Data Systems • Processor • Control I/O • Programming

  8. Instrumentation • GPS • Vitals • Gauges Payload Allocation Power Structure • Satellite • Physical Construction • Parachute Breakdown Structure Detail (cont.)

  9. General Architecture

  10. Satellite Components: Power • Lithium-Ion batteries shall be used • Nominal Voltage: 30V or 15V • Weight: 1300 grams max. (2.86 pounds max.)

  11. Satellite Components: Communication • Antenna • Omni-directional antenna • For amateur television (ATV) transmission on 70cm band (420-440 MHz) • Packet Radio antenna  2 meter dipole

  12. Satellite Components: Communication • Packet Radio • Send and receive command and telemetry data • Transmission in 2 meter band • Total system weight under two pounds

  13. Satellite Components: Communication • Amateur Radio (HAM) License • Must be licensed by FCC to transmit in required bands • Technician Class license is sufficient

  14. Satellite Components: Communication • Video • Transmission in 70 cm band • Ground control records video feed via ATV • System uses small “spy” cameras on satellite

  15. Satellite Components: Data Systems • Processor: BASIC Stamp  Motherboard: Basic Stamp Carrier • Serial Port Interface • Uses external DC power • Memory: 128MB Flash

  16. Satellite Components: Instrumentation • Serial port interface with Data Systems  Monitors external environment • Temperature • Pressure • Humidity

  17. Satellite Components: Structures • Payload Construction – Inner Shell •3/16” thick Sturdy Board • Provides strong shell with insulation  Payload Construction – Outer Shell • Polyurethane Foam • Polystyrene Foam • Cost and availability are factors

  18. Collaborative Efforts National Space Science Technology Center (NSSTC) • Ed Myska • Mark Adrian • Dennis Gallager  National Oceanic and Atmospheric Administration (NOAA) Corpus Christi Office • Jason Dunn

  19. Conclusion • This project meets senior design course requirements for each discipline • Offers students a chance to work under time and budget constraints, as well as with mentors from industry • Allows for a personal exploration of space!
