CSRC Coordinates
Official NGS-sanctioned coordinates for continuous and non-continuous sites included in the re-observation of the California High Precision Geodetic Network HPGN 2000.35 are available in: reference frames. Please note that these coordinates are valid for the 2000.35 epoch.

SOPAC site coordinates   Coordinates from the Scripps Orbit and Permanent Array Center are available through CSRC's partnership with SOPAC. These are not the NGS-sanctioned coordinates.

These coordinates are used as a-priori values in SOPAC's analyses and are valid on the specific epoch listed. Processed coordinates are calculated weekly for many of these sites, and site velocities are then applied to obtain estimated daily coordinates.

SCOUT   The Scripps Coordinate Update Tool generates coordinates of a specific site, given a RINEX file for a particular day. SCOUT does not necessarily use NGS-sanctioned reference sites to calculate precise coordinates. These coordinates are returned in the ITRF2000 reference frame, and are based on daily solutions.

NGS datasheets containing offically-sanctioned coordinates are available for continuous and non-continuous GPS sites in California.
