BalloonSat C.A.T.E.O.S

• Magnetic Field Testing– Measure the earth’s magnetic field during flight– Prove that magnetic field strength varies with

altitude– Determine the orientation of the camera

throughout flight

– Attitude Determination in Satellites

Design

• Science Components– Magnetic field sensor– Faraday Cage

• Satellite Components– AVR Microcontroller– Heater– Camera

Accomplishing the Mission

• Take data during flight• Recover data from magnetic field sensor and

camera• Interpolate data to determine magnetic field

strength and camera orientation• Give Chris a cookie

Organizational ChartPerson Job Specific Tasks

Zachary Cuseo Systems Engineer

This job involves making sure all the different systems work together in order to assure that the mission is successful and the desired data is obtained.

Tyler Knappe Code Monkey

This job involves programming the AVR to work with the rest of the box, specifically to gather data, take pictures, and control the inner temperature of the satellite.

Shweta Maurya Chief Financial Officer and Data Analyst

This job involves creating and editing diagrams and schematics, tempering and overseeing the budget, and translating the data into coherent analysis in LoggerPro software.

Andrew Fruge’Structures and Asst. Systems Engineer

This job involves creating, testing, and improving the outer foam core structure, as well as the Faraday Cage.  Andrew will also assist Zach with part of the Systems Engineering.     

Sydni Smith Internal Structures Engineer

This job involves arranging the inner components and building whatever stands or holders or shelves may be necessary to keep the inside of the satellite organized and in working condition.

Christopher Nie Electrical Engineer

This job involves being responsible for the power system, including the batteries, electrical connections between components, and the specific power requirements between components.
