I don't know if related or not, but years ago there was a system used to
improve the accuracy of GPS, in places like harbours. They would put a
special transmitter at a site. The exact location of the site was known,
and also what error it got from the GPS system, continuously evaluated.
A ship would use that information to correct their error from their own
GPS receiver by comparison with the error on the site nearby. The
resulting precision was maybe one meter.

There is also a system called "High precision positioning" and the
accuracy is even less than a meter.
