I don't see how our government (USA) would ever allow this to happen. The
reason that current GPS have the 30 meter error is to prevent strategic
sites from being located too accurately. If the is a random 30 meter
radius error then hitting a strategic target becomes nearly impossible.
This error is built in by the government for this reason. The government
GPS gear is much more accurate. If you are talking about GPS accurate to
within 1 or 2 meters this could be seen as a threat to the targets that
the current system is designed to protect.
