 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.

Structural Testing – Completed on 10/11 – C.A.T.E.O.S. survived the rigorous testing and remained intact Magnetic Sensor Testing – Completed on 11/4 Cold Test – Completed on 11/1 – All hardware functioned for 90 minutes within a cooler filled with dry ice

 Survived but showed wear on corners Condition of test structure after tests

 Tested sensors independent of the AVR to determine expected range  Connected sensors to the AVR, recorded the data to the AVR, and parsed the data into spreadsheet  This data was compared to the expected values from the initial testing and found to be accurate

 Sample raw data sheet

 Mag_X:  Roughly east/west direction  Mag_Y: (1.60* ) – 3.2 = Gauss

 Internal temperature data from cold test

We expect to see the magnetic field decrease as 1/(Earth’s Radius + d), where d = the altitude during flight. - We expect these results because we are traveling away from the source of the magnetic field, the Earth.  This variation will be shown in the data from the Y-magnetometer

 Expected Mag_X range: 1.733V – 2.333V  2.333V corresponds to the sensor pointing north  1.733V corresponds to the sensor pointing south  2.000V corresponds to the sensor pointing east or west

 Hardware may shut off under extreme cold conditions and/or lack of sufficient insulation  Properly securing camera  Getting sleep

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 hurt Team 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
