[time-nuts] New Japanese GPS accuracy

[Brooke Clarke]

Hi Joe:

I think it's the L1C signal, see:

I remember reading that they want your cell phone to guide you to a 
shop's front door in a multistory building.   There will be ceiling 
mounted pseudo satellites using the same L1C signal to make that work.

Have Fun,
