Small Isn't Just Beautiful, It's Educational For California-Irvine Students Launching Micro Satellite to Photograph the Earth
CONCORD, Mass. - (BUSINESS WIRE) - Building a satellite smaller than a football, packed with delicate
electronics and tough enough to survive a rocket ride into orbit helped
engineering students at the University
of California, Irvine learn that a lot of education can fit in a
really small package.
UCI's cube satellite goes into orbit this December after five years of
re-design, re-manufacture, and transitions on the UCISAT
satellite project team. The team used SolidWorks
CAD software to design the cube satellite's mechanical structure. SolidWorks
Simulation software enabled the team to experiment with different
designs that reduced weight and eliminated interference inside the
satellite, and with materials that could withstand the stresses from
large g-forces. Once deployed, the 10 centimeter (four inch) square
satellite will maintain its orbit with the help of on-board magnets. The
magnets stabilize the satellite while its cell-phone-sized camera
captures images of the Earth and transmits back to the ground station on
the UCI campus. Designing the satellite was an exercise in fitting
photographic and communication electronics into the small structure so
they wouldn't interfere with each other. The student designers also had
to stay under a weight limit of 1.3 kilograms (2.5 pounds), which made
the cube satellite just the kind of challenge they envisioned when they
started the project in 2005.
"The goal was to test our capabilities - to find out how we could make a
functioning satellite with student labor and limited funding," said
fourth-year student Allen Giragosian, leader of UCISAT's mechanical
structures team. "We used SolidWorks to design the external structure
and to model PCB boards and the camera to check for interferences.
Design analysis showed us that some of the PCB components would have
interfered with each other and that the battery was too thick - it hit
one of the circuit boards. SolidWorks helped us correct those problems
so they didn't make it into the final version."
Unlike similar projects at other universities, the UCISAT team built its
cube satellite from the ground up instead of using a kit. UCISAT team
members Anahita
Sidhwa and Timothy Van Name recently brought a prototype of UCI's cube
satellite to the SolidWorks World user group event in Anaheim, where
SolidWorks CEO Jeff Ray held it up as an example of innovation.
"UCI's cube satellite packs a lot of innovation and creativity into a
very small package," said Marie Planchard, director of worldwide
education markets. "The students built the satellite as an intellectual
exercise, but the knowledge and skills they gained by solving problems
like staying under weight and eliminating interference will help them in
the professional world as well. Besides that, how many cooler things can
you have on your resume than 'I built a satellite that's orbiting above
us right now?' "
The university relies on SolidWorks authorize reseller GoEngineer
for ongoing service and support.
