Re: Wow
AFAIK Inertial Navigation System are either very big and expensive, or else not very accurate for large distances / long times as frequently required by location applications. But I guess a combination of multiple satellite systems and a basic INS could be combined into something that can reliably defeat limited local jamming.
I'm not sure it would be possible to defeat a fairly large-scale sophisticated jamming (after all if someone is jamming GPS how difficult is it to also jam Galileo, GLONASS etc?) without using very sophisticated (and therefore expensive and possibly large) INS
