Team Six-Pack Launch Readiness Review Calder Lane, Courtney Ballard, Ian Thom, Thomas Green, Matt Cirbo, Janelle Montoya 11/1/11 Fall 2011 Rev A

Mission Overview BalloonSat Helios measures the efficiency of wireless energy transmission using a laser and solar panels.

Design Overview Two Foam Core Structures Top Circuit: Nine solar panels 3.3 volt Li-ion 50 mW red laser Bottom Circuit: One solar panel Attopilot current and voltage sensor Arduino Uno and SD shield.

Cold Test 1 2 3

Sun-Laser Comparison Test 2 3 1

HOBO Test

Camera Test Camera worked, took over 600 pictures in two hours.

Whip and Drag Tests Whipped at about a two foot length to simulate flight string motion. Satellite dragged as a more accurate test of the satellite’s predicted landing behavior.

Drop Test Satellite dropped from second story to attain a speed of about 20 m/s.

Expected Results Cold test: More voltage as fog cleared –More laser light hitting panel Expect similar results on flight –Less atmosphere means better transmission.

Biggest Worries Resolving amperage issue Final assembly
