Well, the challenge as I see it is not so much in the RF side of things, but being to take advantage of the available (relatively affordable) launch opportunities available (i.e. LEO), then coming up with a way to being able to move the bird into an orbit more suitable. Yes, propulsion hasn't been AMSAT's strong point, but for most of the last 20 years, I only recall LEOs being put up (AO-40 being the only exception I can recall in that timeframe). So the challenge is to find a means of propulsion that is relatively safe, inexpensive and lightweight, but can move a satellite into a significantly higher orbit (e.g. MEO). I'd imagine that such a form of propulsion is probably only found in science fiction, but how close can one get in the real world? Are there any universities working on cheaper ways to move satellites around, once launched, that need a suitable test mass (that happens to have a transponder or two on board)? 73 de VK3JED / VK3IRL http://vkradio.com _______________________________________________ Sent via amsat...@amsat.org.
