[time-nuts] iGPS?

[Chris Albertson]

Anyone know anything about "iGPS"?  Apparently the Iridium low orbit
communications sats are now modified via software update to send
signals that when combined with GPS allow for a receiver that is MUCH
more precise and harder to jam and can work in urban areas better.
Apple just bought a company that is building iGPS receivers.   Looks
like something that they might want to put inside a cell phone but
when you have an orders of magnitude important in position you'd
expect better timing too, or so I would think.

Seems like a very smart idea if all that was required was a software
upload to existing spacecraft.  From what I read this is real, not a
proposal another are real receivers being tested.
