There's not really much that needs to be said about this six-pound beast of a box than what's hinted at in the headline: Basically, this is a portable satellite communications device that's built around an iPhone dock.
Inside the box are a spectrum analyzer, power meter, multimeter and a Low Noise Block Downconverter. The latter of which means, basically, "a contraption that lets you locate and verify and measure satellite and other mobile signals." I have to assume the iPhone dock is there so that you can update your friends on Twitter about the status of the mission in real-time.
