(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A125125 Decimal expansion of the geocentric gravitational constant (mass of Earth's atmosphere included) of the World Geodetic System 1984 Ellipsoid, second upgrade. 4
3, 9, 8, 6, 0, 0, 4, 4, 1, 8 (list; constant; graph; refs; listen; history; text; internal format)



Closely aligned with ITRF93, 29 Sept 96 onwards.

The new World Geodetic System is called WGS 84. It is currently the reference system being used by the Global Positioning System. It is geocentric and globally consistent within +-1 m.
