    GPS is actually not that accurate, it's about down to about 25 meters if you don't use any other enhancment

    GPS is only so accurate because they include Einstein's equations. Otherwise it wouldn't be as accurate.

    also, China recently launched the first satellite of Beidou, their own global navigation satellite system, since they obviously don't want to be dependent on the evil imperialists for their military needs. Within a decade, GPS will no doubt be one of several redundant systems which will allow for continuity of service worldwide.

    @airjaimika private companies won't, but international organizations could. The European Union is in the process of constructing Galileo, a similar sat-nav system; nine of the satellites are already operational. The Russian GLONASS system has been around since the early '90s. The construction of Galileo has partially been driven by fears of the USAF making the system unavailable, but that is highly unlikely as so much of our infrastructure is dependent on GPS.

    @BloatedSensations GPS is a US military system, when the time comes they can turn it off, and also they can add an error to the signals , hence making your equipment useless/inaccurate whilst correcting for the error in their own systems.

    The reason its free for public use is because that way no private company will set up a parallel system that the USAF can not control.

    @BloatedSensations american propaganda is the cancer of the world, I agree.
