Provide a hands-on experience in the full lifecycle of space systems
development for students at UAH, and extend the opportunity to additional
students throughout the country.
- UAH graduate and undergraduate students will have the leading role in all phases
of SEDSAT-1 system development and operation, except where such
involvement is impractical.
- The educational value of the project will be extended to additional universities
through development and operations partnerships with additional universities. We
will seek additional partnerships during the life of the program where they enhance
system capabilities and extend access to the SEDSAT resource.
- A middle school curriculum plan will make use of SEDSAT-1 as a pre-college
resource after SEDSAT-1 launch
Enhance the UAH educational program in space system development
- SEDSAT-1 derived materials will continue to be integrate into UAH
undergraduate and graduate engineering courses to enhance students space
awareness and knowledge
- SEDSAT students will participate in a prototype of the first of several course in
satellite design to be offered at senior and initial graduate levels
- SEDSAT will continue to be used as a resource for significant basic and applied
research by graduate students, including the aforementioned attitude determination
and control work, and work on lossless data compression for scientific imagery
Advance the state of the art in low cost attitude stabilization and control for
microsatellites
- Demonstrate an new attitude determination system using a panoramic annular lens
(PAL), commercial video camera, and image processors
- Demonstrate an new attitude stabilization and control methodology for
microsatellites without passive stabilizers or magnetometers using sliding mode
control of magnetorquers
- Demonstrate integration of an AshTech 12-channel GPS receiver into the control
system. The GPS receiver will be provided by an industrial partner at no cost and
the mapping center at Ohio State will provide graduate student support and direct
mentoring on GPS data processing.
Gather data on the space performance of selected commercial and advanced
electronics technologies
- Gather performance data on IBM Luna error correcting dynamic random access
memories
- Gather performance data on the ARPA/SCC SCC-100 multi-chip module space
computer
- Gather performance data on Nickel Metal Hydride (NiMh) battery cells provided
by Marshall Space Flight Center
- Gather performance data on TRW, Applied Energy, and/or other solar cells
Collect and distribute, as a public resource on the Internet, multi-spectral
remote sensing data, including data specifically targeted at lightning
- SEDSAT will contain a video-based imaging system designed to produce a
resolution of 200 meters in an 800 km orbit
- The imaging system will operate with a filter wheel containing at least ten
narrowband filters chosen to match the edges of major atmospheric absorption
bands, and coordinate with ground based radiometric calibration systems
- On board computing resources will archive all data, and provide an advanced
image browsing system based on progressive lossless compression
- All data downlinked through cooperating ground stations will be forwarded to an
archive center, and accessible through web protocols using standard browsers
and provided plug-ins
Provide packet store-and-forward and analog relay capabilities to the amateur
radio community
