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 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 did john Harrison do using longitude?
John Harrison developed the first practical marine chronometer, H4, to accurately calculate longitude at sea. This invention revolutionized navigation by providing a reliable method for determining a ship's exact position, therefore improving the safety and efficiency of long-distance sea travel. Harrison's work directly contributed to the solving of the "longitude problem" and significantly advanced maritime exploration and trade.
What is an octant used for?
An octant is a navigational instrument used to measure the angle between an astronomical object and the horizon, aiding in celestial navigation. Historically, it was essential for sailors to determine their latitude and longitude at sea. The instrument has a quarter-circle arc and is marked with a scale, allowing for precise measurements. While largely replaced by modern devices like GPS, the octant remains significant in the history of navigation and astronomy.
When did you start using latitude and longitude?
Latitude and longitude have been used for navigation and mapping for centuries. However, the modern system of latitude and longitude was established in the 18th century with the development of accurate methods for determining a ship's position at sea.
What sea is at 41º north latitude 28º east longitude?
That point is about 50 miles west of Istanbul, in the Sea of Marmara.
What is a sexton wheel?
A sexton wheel, also known as a sextant wheel, is a navigational instrument used to measure angles between celestial objects and the horizon. It consists of a graduated arc and a sighting mechanism that allows users to determine their position at sea or in the air by calculating their latitude and longitude. The sexton wheel is essential for celestial navigation and has been historically significant for maritime exploration.

What navigation instrument is used to determine a ship's position at sea?
Astrolabe.
What is the instrument used to send down sound waves in the sea?
an amplifier
What is the tool that sailors used to determine their position at sea?
Sailors traditionally used a sextant to determine their position at sea. This navigational instrument measures the angle between a celestial body, such as the sun or stars, and the horizon. By knowing the time of the measurement and using celestial charts, sailors could calculate their latitude and longitude, helping them navigate accurately across the oceans.
What instrument is used for indicating the depth of the sea beneath a moving vessel?
bathometer
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.
