    The "A" in A-GPS does not come from 12,500 miles away, as their web site asserts.
    The "A" is ephemeris and other over-head info, and in this context is transmitted by the mobile phone network.

    GlobalLocate Corp and SIRF both tout receiver designs that incorporate massively parallel correlator
    technology. This extends GPS receiver sensitivity down to -159dBmW.

    Galileo has been approved. It is compatible Navstar and will more than double the GPS constellation.
    This will provide greater likelihood of favorable signal reception conditions.
