Fall 2011 Rev A 08-16-11 Team Six-PackLaunch Readiness Review Calder Lane, Courtney Ballard, Ian Thom, Thomas Green, Matt Cirbo, Janelle Montoya 11/1/11
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
HOBO Test • 1 2 • 4 • 3
Camera Test Camera worked, took over 600 pictures in two hours.
Whip and Drag Tests Satellite dragged as a more accurate test of the satellite’s predicted landing behavior. Whipped at about a two foot length to simulate flight string motion.
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
