Brian...

Not to downplay the advantages of available Amateur Radio Satellites in your
decision making process but...

Another opportunity to consider is to "piggyback" on someone else's
"non-Amateur Radio" experiment. There are several "experimental" satellites
that currently are controlled by universities and the like. You might be
able to work with them to transmit your test code and have your robot react.

Also you must learn the difference between geo-synchronous(sp) and
polar-orbiting satellites. Current availability of "experimental satellites"
are in the polar orbiting category which might mean, without a significant
antenna, you may only get 10 minutes 2 times a day to attempt your project.

Of course if you can con someone at SIRIUS or XM to open up a channel for
you or play your code, that's another thing. Commercial time on other
Geo-Sync's can be "purchased."

In the Amateur Radio venue, there are also several digital satellites that
exist that might relay your code however your control code would have to
work within the satellite's existing communications parameters.

Consider, as it is an experiment, using a balloon repeater for the initial
demonstration. With that success you can continue to pursue your satellite.
