IGS20

Attributes

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: International GNSS Service (IGS), "Upcoming switch to IGS20", IGSMAIL-8238 and IGSMAIL-8282, https://igs.org/

Revision date: 2023-03-01

Scope: Geodesy.

Remarks: Used for IGS products from GPS week 2238 (2022-11-27). Replaces IGb14. Compared to IGb14, IGS20 contains 98 new stations, mostly in previously sparsely covered areas, but with 25 IGb14 sites removed. For all practical purposes coincident with ITRF2020.

Area of use: World.
