SENIOR TEAM PROJECT WRIGHT STATE UNIVERSITY HIGH ALTITUDE BALLOON Bach le Cullen Naser Husain Mohammad Hassan Project Scope Objective Automatically track High Altitude Balloon o Use existing antennas and control system o APRS data from balloon and/or internet (APRS-IS)

SENIOR TEAM PROJECT WRIGHT STATE UNIVERSITY HIGH ALTITUDE BALLOON Bach le Cullen Naser Husain Mohammad Hassan Project Scope Key Capabilities Real time tracking using GPS information extracted from the balloon APRS-IS packet Real time data acquisition of: o Slow Scan TV (SSTV) on select flights o Analog Amateur TV (ATV) on select flights Secondary gateway for APRS-IS

SENIOR TEAM PROJECT WRIGHT STATE UNIVERSITY HIGH ALTITUDE BALLOON Bach le Cullen Naser Husain Mohammad Hassan Project Scope APRS & GPS Automatic Position Reporting System (APRS) AX.25 Packet Radio AFSK on 2 meters FM (Pos Frame) o # of Satellites Tracked o GPS Quality o Temperature o Battery Voltage o Altitude (Feet) o Speed (Knots) o Heading (Degrees) o Longitude (GPS module) o Latitude (GPS module)

SENIOR TEAM PROJECT WRIGHT STATE UNIVERSITY HIGH ALTITUDE BALLOON Bach le Cullen Naser Husain Mohammad Hassan Project Scope High Altitude Balloon Program - Background Started near-space exploration with the Temperature Satellite project in 2003 o Initiated by advisers, Kumar Yelamarthi and Ruby Mawasha o Funding obtained from the Ohio Space Grant Consortium o Freshman presented this project at a NASA meeting o Received outstanding feedback. Wright State University decided to move forward in the area of near-space exploration. The High Altitude Balloon team (HIBAL) was initiated in 2005 o Advisers - Joseph C. Slater, J. Mitch Wolff, John Wu and Ruby Mawasha o Funding obtained from the Ohio Space Grant Consortium. Major goal: o Launch two senior design experiments each year o Growing sophistication and technology demonstration each time.
