
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

Magnetic Sensor Testing

Completed on 10/11
C.A.T.E.O.S. survived the rigorous testing and
remained intact
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: 2.00687  Roughly east/west direction

Mag_Y: (1.60*1.74807) – 3.2 = -.403088 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
Science
Requirement
Compliance
Measuring Earth’s magnetic field with respect to altitude changes
Analog sensor inputs cannot exceed 5v
Provided 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
A paper clip will be used to secure the tube, as well as hot glue if
needed
A heater system will maintain the temperature of the internal
structure
Mass of payload has been budgeted and is within the requirements
Secure, non-metal flight string tube
Internal temperature must remain above -10 degrees Celsius
Total weight cannot exceed 850g
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 HOBO
Provided, set-up, and accounted for in mass and design
External Temperature Cable
AVR Microcontroller Board and Batteries – 150g
Provided
Provided, set-up, and accounted for in mass and design
Heater - 100g
Provided, set-up, and accounted for in mass and design
Canon Digital Camera - 220g
Provided, to be set-up, and accounted for in mass and design
Foam Core
Provided and is being used for the external structure
Allowance for spare parts on budget and parts list
Some money has been allotted within the budget for spare parts
U.S. Flag and Contact info on outside
Provided and will be attached on external structure
Keep documents and design in metric
Design 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
Team shall use goggles, gloves, and other safety gear when
necessary
Hardware will be securely placed inside the structure to ensure
that it returns in working order
No one shall get hurt
Return hardware to program in working order
All parts paid by Chris Koehler and receipts provided
Turn in receipts within 60 days
Order forms are completed, orders have been made, receipts have
been sent
Additional 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 payload
No living things are being used in the experiment, or in the payload
Complete final report with bonus video
The team plans to make a video and complete report on time
