IGS97

Attributes

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: OGP

Information source: http://www.ngs.noaa.gov/CORS/

Revision date: 2019-05-15

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

Remarks: Used for IGS products from GPS week 1065 through GPS week 1142 (2000-06-04 to 2001-12-01). Replaced by IGS00. For all practical purposes coincident with ITRF97.

Area of use: World.
