[aprssig] APRS Glider packages

[djhuff at rockwellcollins.com]

Actually, that has been done sort of. 
The National Science Foundation gave a few grants for researching this 
type of idea, apparently they thought it could deliver payloads (like 
spare ammunition, parts etc.) to certain areas.

The folks at Great Plains Superlaunch probably can tell you more, they are 
having their convention in Topeka, KS tomorrow, watch for some of their 
balloons tomorrow on APRS.

[aprssig] APRS Glider packages






It would sure be fun to design smart packages...

When dropped from a balloon, each one would glide itself to its
assigned GPS delivery address.  A GPS, a uP, some tiny
actuators, and I would think you could put this into something
the size of a toilet paper tube.  With short stubby wings.

A great student project...
Of course, APRS would track the success of these...
So much fun, so little time.
They would have to be lightweight and "bounceable" so that they
bounce right off of windshields and leave no mark on someones
hood...

But Gravity is a pretty reliable propulsion system...
