Budget Satellite

the middies were laughed at when they proposed a budget satellite for 50K. Boeing said it couldn't be done and gave them 250K. Well now they can build five more because the smart minds on the bay have built one."
"And they were innovative - they discovered that the tape in a tape measure would flip into place on its own while in orbit."
We remember the last space venture battling metric versus auxiliary measurement systems.
(I'm sorry NASA. You guys do wonderful things. I just couldn't resist.)

The MacGyver satellite
Several students at my school, Leland High, decided that we should undertake a challenge unlike any other. A goal was set to be the first high school to launch a satellite into outer space and have it communicate back with earth, as vaguely mentioned in a Slashback. This particular program is called Cubesat, but only consisted exclusively of universities and private corporations/citizens until we came along.
Much like the engineers in this article, we are using off-the-shelf parts to build our satellite, albeit not from Radio Shack since Radio Shacks don't seem to carry much in San Jose. The antenna we are designing exemplifies the simplicity of the components. In theory, guitar string or the wire used in braces would do the job easily. Our power system is even more simple: d-sized lithium batteries (non-rechargable) linked together.
The parts for our Cubesat will cost less than $5,000, more likely less than $1,000. We are hoping that our prototype will function properly during a test launch on an amateur rocket. After that, designing the antenna configuration (for those who are knowledgable about radio, our cube-shaped satellite forms a poor ground plane and we are also confined to a difficult broadcast frequency) and internal layout (to ensure that our satellite has a perfect center of gravity).
You can reach the webpage for the Leland Cubesat team here. Be forewarned, some of the information is slightly out of date at the moment. I will do my best to fix that as soon as possible, but priorities lie elsewhere at the moment.
Hell, I wish them the best of luck. I hope the satellite lasts them 5 years instead of one. The idea here ISN'T making satellites out of cheap parts, its coming up with less expensive ways to accomplish the tasks needed to operate a saltellite. Sure using a tape measure for an antenna sounds hokey, but maybe it'll give the professionals some ideas for the future (gee antennas that unroll on their own instead of requriing some advanced deployment system that only gets used once) etc.
For as much as folks bitch about the gov't here, I think if a few students decide to show that a satellite CAN be constructed cheaply - more power to them. The information they gather will be very useful. Yes, sure, the launch costs aren't part of the $50K, but that wasn't part of the equation. Most satellites themselves WITHOUT launch costs are millions and millions of dollars. Nobody said they could launch it and build it for < $50K. So they hitch a ride on a rocket going up anyway. Remember, this thing is pretty small and it probably is tucked into the payload bay where a normal size satellite wouldn't fit.
But even if it isn't. I'd think geeks like us would be proud that some students got laughed at when applying for the grant and managed to pull it off through some everyday common sense and ingenuity. I say good luck and I hope everything works as planned!

UoSAT-1, if I remember correctly (details are sparse on the net) was build on a budget of 60,000 as a student project and piggybacked into orbit on an Ariane-4 comsat launch. A number of subsequent UoSATs are part of the OSCAR series of radio amateur satellites, and a commercial spin-off of the University, SSTL (Surrey Satellite Technology Limited) build and sell minisats in the 200-500Kg rangefor commercial purchasers; see, for example, this report of the launch of UoSAT-12 (from 1999).
