University & Student Involvement 25 universities and >2500 students since 1999
Three Corner Sat (University NanoSat 1/2) Delta-IV Heavy Liftoff Nanosat-2 aloft Demosat on Delta IV Heavy Project Objective • Provide flight demonstration capability to two AFRL SBIR-developed low shock release devices • Study ionospheric disturbances • Measure upper atmosphere cloud formation • Simulate formation flying capability Technical Innovation / Approach • Three nearly identical independent satellites built by three separate universities • Each university plus AFRL launcher combined to form Nanosat-2 Impacts / Benefits • Education legacy of the Future Aerospace Workforce • Advertisement of AFRL for recruitment • Dec 2004 – Nanosat-2 Three Corner Satellite (3CS) Launched on the first Delta IV Heavy Demo Mission
(Formation Autonomous Satellite with Thrust, Relnav & Crosslink) OBJECTIVE: Primary: Low-cost, small, precise GPS rel-nav metrology Secondary: Demo motorized Lightband separation system & Micro-Discharge Plasma Thruster DESCRIPTION One satellite maintains orbit altitude, the other is a drifting “control” Verified by GPS telemetry, potentially by ground-based tracking FASTRAC (University NanoSat 3) http://fastrac.ae.utexas.edu/
CUSat (University NanoSat-4) http://cusat.cornell.edu/ OBJECTIVE • Demonstrate and verify on orbit Carrier-phase Differential GPS for relative navigation • Demonstrate an end-to-end autonomous on orbit visual inspection system. DESCRIPTION • Centimeter-level accurate Carrier-phase Differential GPS • Cameras to gather target-satellite imagery • Image-processing techniques to verify the CDGPS relative distance and orientation estimates Generation of a 3D model of the target satellite for the user.
NanoSat-5 • Competition in progress • Eleven schools participating • Missions varied from ionospheric observations, to autonomous separation and GPS navigation, to remote sensing using GPS signals. • Preliminary Design Review (PDR) will occur in August 2007 at the USU SmallSat Conference.
AFRL Sponsored Activities • Hands-on Standard Sat-Fab Practices • Aerospace Engineering Facility (AEF) @ KAFB • Includes clean room procedures, elec/mech fab • All Universities participate (~50 Students on-site) • Formal Review Process • SCR (System Concept) (t = 0) • Internal AFRL/NASA review (telecon) • PDR (6 months @ SmallSat, Logan, UT) • ~20 Industry/Government reviewers • CDR (~1 year @ each university campus) • AFRL + selected others (industry) experts • Proto-Qualification Review (1.5 years, @ SmallSat) • Format as PDR w/ fully-built EDU • FCR (Flight Competition) (2 years, Location varies) • Formal Panel of Judges and Criteria w/ downselect NS-4 PDR, Logan, UT, August 2005
