[ Update this Record ]

Summary
Abstract: The National Geodetic Survey (NGS) provides precise orbital positions
and velocities for the NAVSTAR Global Positioning System (GPS) satellite
constellation. This data is computed from satellite tracking data collected in
the United States and other countries. The NGS ephemeris data is computed and
distributed using coordinates and station velocities published in the Annual
Report for 1990 of ... View entire text
