Just had a look at your blog, very interesting stuff. Seems like you're mostly looking at Beam + IMU guidance which is an interesting method, especially since it doesn't add to the expense aside from reflectors on the rocket.
The satellite concept I'm not entirely sure about - it'll need to be verifiable by quite a few amateurs around the world I think, and tracking a small sphere I think would prove extremely tricky.
sounds like you've come a fair way in testing propulsion though and that's really cool to hear. Wish you the best of luck!
I've yet to cover ignition and I'm not looking forward to tackling the problem...
