What is WGS 84?
The Global Positioning System uses the World Geodetic System (WGS84) as its reference coordinate system. It consists of a reference ellipsoid, a standard coordinate system, altitude data, and a geoid.

Sep 4, 2024 · The WGS 84 coordinate system is the standard U.S. Department of Defense definition of a global reference system for geospatial information. It is compatible with the Global Positioning System (GPS) and serves as the reference system for navigation systems and GIS.
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS. The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
2 days ago · A Coordinate reference system (CRS) defines, with the help of coordinates, how the two-dimensional, projected map is related to real locations on the earth. There are two different types of coordinate reference systems: Geographic Coordinate Systems and Projected Coordinate Systems .
Jun 5, 2024 · WGS84 is a three-dimensional coordinate reference frame and the current world geodetic system standard used in navigation, mapping, drones, self-driving cars, robotics, satellite communications, and geospatial analysis.
WGS84 was adopted by ICAO as the standard navigation reference system for international civil aviation in 1989. The vast majority of the world's nations currently use the WGS84 standard to publish waypoint coordinates for navigation inclusive of airports, runways, navigation aids and intersections.
WGS 84 is the standard U.S. Department of Defense definition of a global reference system for geospatial information and is the reference system for the Global Positioning System (GPS). It is compatible with the International Terrestrial Reference System (ITRS).
