BalloonSat Aquintus Mission Statement The BalloonSat Aquintus shall ascend to an altitude of approximately 30,000 meters to carry out scientific experiments that will measure the tilt of the satellite, forces acting upon it, wind speed, and solar energy to better understand the conditions in which high altitude observatories would be in.

Experiments Solar Panel Experiment The purpose of this experiment is to test the efficiency of solar panels at high altitudes. However, we will measure efficiency as a function of peak power. Accelerometer Experiment The accelerometer we have acquired will measure the tilt of our ballonsat relative to the surface of the Earth.

Wind speed sensor Composed of 4 thermistors around a cylindrical structure. Measure temperature changes made by different wind speeds through voltage variations. Compare temperature differences to results from Earth to extrapolate wind speed.

Top Level Objectives (O1) Construct BalloonSat to improve understanding of environmental conditions at 30,000 meters for under $200 dollars by November 10th 2007. (O2) Measure tilt in z axis (perpendicular to surface) and G forces within a range of -3 to 3 Gs a function of altitude in the range of 30,000 meters. (O3) Measure wind speed perpendicular to any of the faces that are parallel to the balloon cord of the BalloonSat as well as solar energy as a function of altitude.

Second Level Requirements S1 (O1/O2) The BalloonSat system shall ascend to a near space altitude. S2 (O2/O3) The BalloonSat system shall carry out scientific experiments of relevance for the future design of airborne telescope observatories S3 (O2/O3) The BalloonSat system shall store the data from the measurements for later recovery on the ground. S4 (O1) The BalloonSat system shall not exceed the dimension limitations of weight and volume S5 (O1) The BalloonSat system shall not be a one-time flight design but shall be ready for another launch after a week from recovery from the first mission. S6 The BalloonSat system shall comply with FAA regulations.
