The U.S. Department of Commerce requires that all exportable GPS products contain performance limitations so that they cannot be used in a manner that could threaten the security of the United States. The following limitations are implemented on the Trimble…
What does the actual real time computation? The phone or the GPS chipset?
Domestic GPS is plenty accurate to use in weapons. It must be accurate to <1M to be useful for navigation. If google maps can find your iphone in your house a missile can too.
I suspect that the Government has plans to make the signal less accurate or even turn it off in the case of an emergency.
GPS is also trivial to jam or spoof since the signals are weak anyway. In Ukraine the EW space is so flooded that they use wired drones, and old rockets with inertial navigation are popular.

I saw some videos about those drones with controlled via fiber cables, crazy tech
The built-in GPS limits are for speed and height, not accuracy.
