WGS84 bounds:
179.9 -85.0
-179.9 85.0

Attributes

Ellipsoid: WGS 84

Prime meridian: Greenwich

Degree from Greenwich: 0

Data source: OGP

Information source: DMA TR8350.2, .

Revision date: 2016-07-02

Scope: GPS satellite navigation (broadcast ephemeris) from 1987-01-01 to 1994-06-28. (Precise ephemeris from 1987-01-01 to 1994-01-01).

Remarks: The NSWC 9Z-2 origin shifted by -4.5 m along the Z-axis, scale changed by -0.6 x 10E-6 and the reference meridian rotated westward by 0.814" to be aligned to the BTS at epoch 1984.0. Replaced by World Geodetic System 1984 (G730) from 1994-06-29.

Area of use: World.
