@Rich... I have a Garmin Montana 600, which appears to have a supper sensitive receiver as it can grab signals and maintain a fix even in my basement...
My Smartphones that use aGPS also have no trouble getting a fix indoors, although at best, an aGPS receiver has about 1 meter accuracy. Need DGPS and long sample times to do better than that. A GPS without cell tower assistance will be 2-3 meters under optimum conditions.
There are some designs for "indoor GPS" that we might start seeing in large buildings like malls and convention centers. Will probably use a combination of WiFi and/or Bluetooth triangulation and require smartphone software or new receivers to work. Standards are a long way off, but some pioneers may start deploying their own solutions before any standards are published.
Earlier designs used transmitters that spoofed or re-transmitted the GPS signals indoors, but at least in the USA they ran afoul of the FCC and DOD so those ideas are essentially dead.
