AMSAT Fox Satellite Program Tony Monteiro, AA2TX VP, Engineering AMSAT Forum Dayton Hamvention 2012
Fox Strategy • Take advantage of large and growing interest in CubeSats • Develop family of CubeSats that would be attractive for flying science missions • Partner with universities and apply for free launches as science missions • After/during science mission, satellite runs amateur radio transponder
Fox Stages • Fox-1 satellites - FM Transponder • First Fox-1 mission - Penn State MEMS Experiment • Launch secured through NASA ELaNa program • Launch Target - 2nd Half 2013 • Fox-2 satellites - Software Defined Transponders (SDX) • Fox-2 missions - linear and digital modes
Fox-1 Operational Modes • Transponder Mode • FM repeater • Telemetry/experiment data sent as sub-audible, low-speed FSK simultaneously • Command Mode • High-speed data (9600 bps) • Science missions with high data/power requirements • Not needed for initial Fox-1 mission - will be activated on-orbit to test capability for future use
Fox-1 "ZombieSat" Features • Intended to extend usable life beyond design target • Designed to operate while in sunlight even with dead (shorted) battery • FM Transponder will operate automatically if microprocessor should fail
Fox-1 Science Experiment • Penn State University • AMSAT sponsored senior design project • 3-axis MEMs gyro sensors • Measures satellite spin rate, spin direction and wobble about magnetic axis • Educational component key element of the NASA ELaNa launch application
Fox-1 Progress • Concept of Operations - Sept 2011 • System Requirements spec - Oct 2011 • Applied to NASA ELaNa program - Nov 2011 • Accepted into NASA ELaNa program - Feb 2012 • Preliminary Design Review - April 2012 • Currently working on first engineering prototype
RF System Fox-1 Satellite Power System Solar Panels Battery Power bus 70 cm Antenna 2 m Antenna Science Experiment IHU Attitude Control
Future Launch Opportunity • Auburn University, University of Alabama, AMSAT • National Science Foundation grant • Pair of satellites based on Fox-1 • 1-year science mission - atmospheric physics • Includes free launch • Submitted May 7, 2012
Proposals for Future Launches • NASA Edison program • AMSAT partner in 3 phase-1 proposals • All 3 proposals accepted by NASA for Phase-2 • Phase-2 proposals due May 22 • Next NASA ELaNa program opening - August 2012 • University partner on Fox-1 mission
