CC, the G* signal quality and reliability seems to be very significantly better than Iridium by all accounts I've seen from those who used both services. How much of that superiority was foreseeable by engineers reading specs as opposed to Iridium failing to meet it's own requirements isn't clear to me.

I know the G* vocoder rate is higher than Iridium's. That accounts for some of the better voice quality. I recall that space-switching performed by Irid was claimed to add signal delay and reduce call connection reliability-maybe we're seeing some of that, too. CDMA vs TDMA? I don't know whether that accounts for some of the quality differential, as well.
