Target entity: WGS 84
Context triple: [GPS space segment, usesReferenceFrame, WGS 84]
  • A. WGS84 chosen
    WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
  • B. GRS80
    GRS80 is a geodetic reference ellipsoid defined in 1980 that serves as a standard mathematical model of the Earth's shape for modern mapping and surveying systems.
  • C. Lambert-93
    Lambert-93 is a French national projected coordinate reference system based on the Lambert conformal conic projection, widely used for mapping and geospatial data across mainland France.
  • D. North American Datum of 1983
    North American Datum of 1983 is a geodetic reference system used across North America to define precise locations on the Earth's surface for mapping, surveying, and navigation.
  • E. International Terrestrial Reference System
    The International Terrestrial Reference System is a globally standardized, Earth-centered coordinate framework used for precise positioning, navigation, and geodetic measurements.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
