Conceptual Design Review for “The Stabilizer”

Mission Overview

• Objective: Our satellite “The Stabilizer” shall ascend to 30 kilometers carrying a CCD video camera that will record a fixed image of the Earth throughout the flight

• We intend to prove that image stabilization on a near space balloon satellite without a complex, fallible mechanisms is possible

• The idea of image stabilization on a near space satellite is relatively unexplored and could yield to a wider variety of uses for near space satellites.

Team Cosmos, The Stabilizer

Design: Structure

• 20x30x20cm foam core box

• 15x19cm Plexiglas window for optimal imaging

• Aluminum tape and hot glue for holding structure together

• Insulation

Team Cosmos, The Stabilizer

Design: Stabilization System• Gyroscopic system• Half-circular brackets• System of bearings• Sits above plexiglas

window• Batteries and storage for

camera shall be attached to prevent interference

• Will keep camera from being affected by motion of satellite

All adds up to…

• Total cost of project: ~$81.14

• Total weight of materials: <870 grams

• The rest of our weight budget will be used for insulation and structural support.

Biggest Worries

• Our bearings not being loose enough

• Structural integrity of the dome

• Maintaining temperature with plastic as part of a wall

• Memory for the CCD camera
