    My iPhone's GPS works inside my house and car, but I thought Iridium only worked on a direct signal. It was meant for outdoor use. Perhaps I'm incorrect.

    Your iPhone uses more than GPS to estimate your position.  It also uses the cellular network and the wifi network you are connected to

    Exactly, it's called aGPS (assisted GPS). The cellular networks won't always pinpoint your exact location, but wifi will.

    To take advantage of their software, I'm assuming it would need updated hardware in order to receive data from the Iridium satellites. Correct?

    Current GPS is accurate to within 12 to 25 feet.  This probably is accurate to 1-2 feet.


    This is not so much for autonomous driving cars.  It is for personal high-accuracy location WITHIN BUILDINGS and outdoors.

    Can you post a link to your source for that data? It sounds totally made up to me. Neither GPS nor Iridium signals pass through walls and neither permits 2 ft accuracy without a DGPS mast very nearby. You cannot (and will never be able to) do navigation indoors using satellites - it defies physics - so I think somebody has been telling you lies. Any RF with a shorter wavelength than 1GHz struggles to pass through a sheet of glass - let alone a building's roof.
