NavSpark: Arduino Compatible with GPS GNSS Receiver

Yes but that somewhat limits the practicality because you need two receivers, a clear signal path between them and one has to be relatively static.

It's fine for surveying but for dynamic applications which are far more common, it's a pain.

You can receive RTK corrections over IP (via a cellular connection). Government bodies across the US push the data over IP to you if you register for a free account.

Then you engineer another source of correction and incorporate that into your project.

The US Navy has been doing accurate position determination using ZERO satellite availability. How do you think a submarine knows where it is?

In agriculture, it is not uncommon to get correction data over mobile data connections, where the static receiver is provided by a third-party service provider.
