Historically, latitude was always measured with the sextant, and
longitude with the chronograph (clock). Nowadays, it's all GPS.
-------------------
The "sextant", from the latin word for "six", is one-sixth of a circle, and is the primary tool used in celestial navigation. However, before the sextant came into widespread use, the "quadrant" of a quarter-circle and the later "octant", an eighth of a circle, were used.

What did john Harrison do using longitude?
John Harrison was a self-educated English carpenter and clockmakerwho invented the marine chronometer, a long-sought-after device for solving the problem of calculating longitude while at sea.
What can one measure with a marine chronometer?
A marine chronometer measures time. It is a very precise instrument because it can also be used to measure the longitude of the ship at sea using the time shown and the angle of the sun.

What sea is 40 degrees north longitude and 51 degrees east longitude?
Caspian Sea
What inventions made exploration possible?
The sextant. An astronomical instrument used to determine latitude and longitude at sea by measuring angular distances, esp. the altitudes of sun, moon, and stars. The chronometer. An extremely accurate clock or other timepiece. Chronometers are used in scientific experiments, navigation, and astronomical observations. It was the invention of a chronometer capable of being used aboard ship, in 1762, that allowed navigators for the first time to accurately determine their longitude at sea.
