1. Team Magnaritaville Final Presentation Zachary Cuseo, Andrew Fruge’, Tyler Knappe, Christopher Nie, Sydni Smith, and Shweta Maurya December 1, 2009

2. Mission Overview The twofold purpose of this BalloonSat mission will be to show that the Earth's magnetic field varies and to show that magnetometers can be used to determine the attitude of a BalloonSat.

3. Mission Overview Continued Hypothesis – Fluctuation in the Earth’s magnetic field – Finding a vector which will facilitate in determining in which direction the camera is pointed Satellite attitude To better understand the magnetic field

4. Mission Specific Components -1 AVR Microcontroller -2 Magnetometers -2 Analog Proto Board Connectors -5 9V Batteries -1 Canon Camera -1 Heater -1 HOBO

5. Functional Block Diagram

6. Functionality Switch Batteries HOBO External Heater AVR Temperature Probe Magnetometers Accelerometer Camera Internal Temperature Probe Pressure Sensors

7. Design Differences Proposed Staggering the Heater, Batteries and AVR for balance. The two magnetometers will extend from opposite sides of the Satellite. There will be a photo of a cheeseburger to truly be C.A.T.E.O.S. Utilizing a Faraday Cage Actual The Heater and Batteries were placed in a corner to maximize heating efficiency, while the AVR was attached to a wall. The two magnetometers extended from adjacent sides for more accurate readings No photo of a cheeseburger was used. No Faraday Cage was necessary.

8. Results and Analysis Mag X Mag Y Strength (nT) Time

9. Results and Analysis Accel X Accel Y Internal Temp (°C) Pressure (psi)

10. Results and Analysis Vertical Mag Y Strength (nT) Time Voltage Time

11. Results and Analysis Vertical field trends – – Overall decrease of 4,219 nT – Expected change due to altitude of 1,694 nT – Rolling into x-direction would explain this extra variation

12. Results and Analysis Magnetometer Data X-Magnetometer Variation

13. Results and Analysis Picture 771 – 8:08 a.m. Data point (28,039, 1.94339)  East

14. Results and Analysis Picture 705 – 7:45 a.m. Data point (21,379, 2.2266)  North

15. Lessons Learned Orient vertical magnetometer pointing down Add a third magnetometer in the horizontal plane for definitive attitude determination Prototype structure – Keep it simple – Test different designs for an efficient use of space

16. Ready to Fly Store payload in standard conditions upright to protect magnetometers Perform launch checklist

17. Failure Analysis No in-flight failures On functional test, y magnetometer was discovered to be inoperative – Thought to be connection problem – Found faulty connection to the proto board – Soldered and verified to be working Magnetometer Structural Failure – End cap lost during transport to launch site – Wax paper taped onto end at launch site

18. Conclusion Discovered a change in the vertical component of the magnetic field with respect to altitude Confirmed a spin in the satellite, as seen through the sinusoidal data Discovered attitude determination is possible with the use of a horizontal magnetometer

19. RFP Compliance RequirementCompliance ScienceMeasuring Earth’s magnetic field with respect to altitude changes Analog sensor inputs cannot exceed 5vProvided sensors and magnetometers use 5V DC Ready to fly again after flight Structure will be tested thoroughly in order to ensure the ability to fly again after flight Secure, non-metal flight string tube A paper clip will be used to secure the tube, as well as hot glue if needed Internal temperature must remain above -10 degrees Celsius A heater system will maintain the temperature of the internal structure Total weight cannot exceed 850gMass of payload has been budgeted and is within the requirements Acquire ascent and descent rates of flight The design will be constructed to withstand the changes in pressure and high speeds during ascent and descent Design shall allow for a 30g HOBOProvided, set-up, and accounted for in mass and design External Temperature CableProvided AVR Microcontroller Board and Batteries – 150gProvided, set-up, and accounted for in mass and design Heater - 100gProvided, set-up, and accounted for in mass and design Canon Digital Camera - 220gProvided, to be set-up, and accounted for in mass and design Foam CoreProvided and is being used for the external structure Allowance for spare parts on budget and parts listSome money has been allotted within the budget for spare parts U.S. Flag and Contact info on outsideProvided and will be attached on external structure Keep documents and design in metricDesign and documents are consistently kept in metric units Launch on November 7, 2009 The team has created a schedule which accommodates for launch date on 11/7 No one shall get hurtTeam shall use goggles, gloves, and other safety gear when necessary Return hardware to program in working order Hardware will be securely placed inside the structure to ensure that it returns in working order All parts paid by Chris Koehler and receipts provided Order forms are completed, orders have been made, receipts have been sent Turn in receipts within 60 daysAdditional receipts will be sent when purchases are made Have fun and be creative Team Magnaritaville is having fun and being creative with its satellite, Cheeseburger at the Edge of Space No living things on payloadNo living things are being used in the experiment, or in the payload Complete final report with bonus videoThe team plans to make a video and complete report on time

21. Message to Next Semester Keep the experiment simple, but make sure everyone is interested in it. Find a way to sufficiently secure the camera and to cover/insulate it. Establish a consistent time to meet on a weekly basis. Do this as early as possible. Utilize your resources (Space grant, your professors, etc.) Start video taping early Prepare for this project to be a major time commitment – Dedicate at least one all-nighter to the satellite
