The Transglobe Expedition (1979–1982) was the first expedition to make a longitudinal (north–south) circumnavigation of the Earth using only surface transport. British adventurer Sir Ranulph Fiennes led a team, including Oliver Shepard and Charles R. Burton, that attempted to follow the Greenwich meridian over both land and water.
Terry W. Virts and Hamish Harding, 11 July 2019, fastest circumnavigation of the globe via the North and South Poles. Virts and Harding headed a crew of eight in a Gulfstream G650ER jet to circumnavigate the globe in a time of 46 hours, 40 minutes and 22 seconds, with an average speed of 860.95 km/h (534.97 mph).
This article focuses on the circumnavigation of Earth. The first circumnavigation of the Earth was the Magellan Expedition, which sailed from Sanlucar de Barrameda, Spain in 1519 and returned in 1522, after crossing the Atlantic, Pacific, and Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth ...
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
During July 9–11, 2019, One More Orbit shattered the Round-the-World record for any aircraft by navigating over both the North and South poles. [7] They completed the fastest Circumnavigation of the Earth via both the Poles in just 46 hours and 40 minutes, cruising at an average speed of 465 knots (535 mph or 861 km/h).
But because Earth is spherical, in reality it will have travelled along three sides of a triangle, and arrive back very close to its starting point. If the starting point is the North Pole, it would have travelled due south from the North Pole to the equator, then west for a quarter of the way around Earth, and then due north back to the North ...
The latitude of the North Pole is 90° N, and the latitude of the South Pole is 90° S. [17] Mariners calculated latitude in the Northern Hemisphere by sighting the pole star with a sextant and using sight reduction tables to correct for height of eye and atmospheric refraction. The height of Polaris in degrees above the horizon is the latitude ...
North of the tropic are the subtropics and the North Temperate Zone. The equivalent line of latitude south of the Equator is called the Tropic of Capricorn, and the region between the two, centered on the Equator, is the tropics. In the year 2000, more than half of the world's population lived north of the Tropic of Cancer. [4]
