Scope: Geodesy. GPS satellite ephemerides produced by US NGS and other International GNSS Service (IGS) analysis centres are expressed in this CRS.

Remarks: Adopted by the International GNSS Service (IGS) from GPS week 1632 (2011-04-17). Updated to IGb08 from GPS week 1709 (2012-10-07).

Area of use: World.

Coordinate system: Earth centred, earth fixed, righthanded 3D coordinate system, consisting of 3 orthogonal axes with X and Y axes in the equatorial plane, positive Z-axis parallel to mean earth rotation axis and pointing towards North Pole. UoM: m.
