What is the actual error of the gps?

gps smartphone cellphone cell-phone mobile map

If you search the map on your smartphone, there are some errors.

I heard that this is due to the gps error, but how much is the actual error of gps?

It must be hard to communicate with satellites because it is far away, right?

It's not a technical problem that there's an error
In fact, it can be reduced to an error of less than 1cm, but they said they wouldn't reduce it on purpose
The U.S. has satellites that are used in gps, but generally people use them with an error of about 10 meters
In the United States, it's not allowed to be used for military purposes
It could be a military problem if other countries use it
