How did the Brits do it?

The Allies did something similar with a German (naval) navigation
system, which turned out to be so efficient that it survived the war
a long time.

First ever LORAN station.

It covered the Bay of Biscay and was heavily utilised by
RAF Coastal Command. They kept that site running for something like
30 years after the war. It was doubtless of more use to the Brits than
the Germans. IIRC, it was *intended* for use by U-Boats but it probably
contributed to the loss of more than it helped.

The Germans had functional radio nav aids that covered the British Isles
from the outset. Knickebein and (later) X-Gerat and Y-Gerat had to be
discovered and jamming methods worked out.
All the above is covered in great detail in "Most Secret War" by R.V.
