  1. AMSAT-NA FOX Satellite Program Review, Status, and Future Jerry Buxton, nØjy AMSAT Vp-engineering

  2. Review FOX-1 - Why it is, what it is

  3. Fox Development Strategy • Take advantage of large and growing interest in CubeSats • Develop family of CubeSats with ham radio transponders that are attractive for hosting science experiments • Partner with universities to develop joint science and education missions • Get a free launch via the NASA ELaNa program

  4. Fox-1: AMSAT-NA’s First CubeSat • Smallest satellite previously built by AMSAT-NA was a 25 cm (approximately 10 inch) cube • Fox-1 is10 cm (approximately 4 inches) per side • Miniaturization not attempted before by AMSAT-NA • Coaxing maximum power from limited solar panel area • Insure stability and robustness of the avionics bus in the environment of space • Success gives us CubeSat design heritage and puts AMSAT-NA back in space

  5. Fox -1 CubeSat • Mission Description: To inspire, engage and educate the next generation • Two-way FM communications transponder • MEMS Gyro Experiment (Penn State) • Low Energy Proton Experiment (Vanderbilt) • JPEG Camera (Virginia Tech) Size: 1U Mass: 1.33 kg RF Power: 800 mW max

  6. University Experiment Payloads on Fox-1 Virginia Tech “EXP4” Filler/Lens Hole VT Camera Vanderbilt “EXP1” Vanderbilt Sensors Vanderbilt Controller Penn State - Erie MEMS Gyros (on IHU board)

  22. Status FOX-1 – where we are, what is next

  23. Two Launch Opportunities! • May 1 2015 on ELaNaXI – possible if there’s a “vacancy” • AFSPC “ULTRASat” mission • Planned orbit is 389 km x 700 km @ 58 degrees inclination • Expected orbit lifetime is 6.5 years • August 2015 on ELaNa XII – MOST LIKELY • NRO “GRACE” mission – our original manifest • Planned orbit is 470 km x 780 km @ 64 degrees inclination • Expected orbit lifetime is 11 years

  26. Our Ride (example)

  27. Fox-1 StatusMilestones • May – Engineering Unit Integration and Testing • June – Critical Design Review • August – Flight Model and Flight Spare complete “Day In The Life” testing • September – Vibration Testing and Thermal Vacuum (bakeout) complete • September – Mission Readiness Review • October – Completion and “Hands Off” • Fox-1 sits on the shelf waiting for delivery in January 2015

  28. Fox-1 StatusFox-1B “RadFXSat” (CSLI 4 Feb 2013) • Use Flight Spare hardware from Fox-1 • Flight Spare experiments from Fox-1 returned to partners • Vanderbilt RadFXSat experiment installed • Operates simultaneously with Transponder • Reset and start again • CDR, Flight Model and Flight Spare integration and testing, Launch provider required testing, Deliver to launch provider • Ready in Second Half 2015

  29. Fox-1 StatusFox-1C and Fox-1D • On the shelf and ready to fly, requiring only solar cells • (Of course, all of the other integration and testing is still required!) • Looking for university partners • You provide the experiments, we provide the communications for your data • Partner for launch opportunities • Amateur radio transponder during or after experiment phase EXP4 EXP3 EXP2 EXP1

  30. Future Fox-2 and beyond

  31. Fox-2 • Flight heritage and track record from Fox-1 series • 3U CubeSat • Software Defined Transponder • Higher power, more modes/bands • Attitude Determination and Control • Development underway

  32. And Beyond… • CubeSat market has not yet reached a plateau • Larger sizes are becoming more common • 3U, 6U, even 12U • Exploration and research leading to expanded possibilities • Propulsion - higher orbits (but not allowed on ELaNa) • Satellites in formation • Several possibilities and partnerships being explored • We are ALWAYS exploring new opportunities!
