GPS Satellite Antenna Phase Center Locations from CDDIS

Daily files contain antenna phase center locations relative to GPS satellite centers of mass. The product is generated at JPL's Global Differential GPS Operations Centers and distributed by NASA's CDDIS.

Use Cases

• Precise orbit determination by modeling satellite antenna phase center offsets.
• Improving GNSS positioning accuracy for geodetic reference frame maintenance.
• Calibrating satellite antenna models used in atmospheric and ionospheric studies.

Strengths

• Data is produced by JPL's Global Differential GPS Operations Centers, a leading authority in GNSS.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating its importance and reliability.

Limitations

• Specific row counts, column names, and file sizes are not provided by any source.
• Sources conflict on license details, with some listing 'other-license-specified' and others 'None'.
