A technological development that permitted sailors to estimate how far east and west they are is the invention of portable, reliable timepieces. There is a wonderful non-fiction book about this called "Longitude" by Dave Sobel.

The concept of time based navigation had been around for quite a while, but it took a long concerted effort to develop the tools necessary. John Harrison developed his first mechanical chronometer over seven years and tested it at sea for the first time in 1738.
As was said above, North-South navigation has been around since prehistory.
