A prime meridian is the meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Any prime meridian is geographically and mathematically defined and is located at the 0-degree longitude and therefore is used as the base point for other longitudes which are measured in the degrees to the west or east of the prime meridian they are located.

With the introduction of satellite technology, it became possible to create a more accurate and detailed global map. With these advances there also arose the necessity to define a reference meridian that, whilst being derived from the Airy Transit Circle, would also take into account the effects of plate movement and variations in the way that the Earth was spinning. For celestial objects that are tidally locked (more specifically, synchronous), however, their prime meridians are determined by the face always inward of the orbit (a planet facing its star, or a moon facing its planet), just as equators are determined by rotation.

Today it is defined by the position of the Airy transit The Greenwich Meridian was chosen to become the Prime Meridian of the World. Beginning in 1973 the International Time Bureau and later the International Earth Rotation and Reference Systems Service changed from reliance on optical instruments like the Airy Transit Circle to techniques such as lunar laser ranging, satellite laser ranging, and very-long-baseline interferometry. On Earth, starting at the North Pole and heading south to the South Pole, the IERS Reference Meridian (as of 2016) passes through: As on the Earth, prime meridians must be arbitrarily defined. Voting took place on 13 October and the resolutions were adopted on 22 October 1884.
