GLONASS Antenna Phase Maps Metadata for Real-Time POD

Metadata files provide names and URLs for antenna phase map data used in real-time GLONASS Precise Orbit Determination (POD) processing. The dataset includes the IGS ANTEX file name and identifies the real-time filter source for related POD products. These files are generated by JPL's Global Differential GPS Operations Centers and distributed by NASA's CDDIS.

Use Cases

• Identifying the specific IGS ANTEX file used for GLONASS POD processing.
• Tracing the real-time filter source for 'pos', 'quat', and 'tdp' GLONASS POD products.
• Providing reference URLs for accessing the underlying antenna phase map data files.

Strengths

• Data is produced by JPL's Global Differential GPS Operations Centers, a leading authority in GNSS.
• The dataset is hosted on multiple platforms (NASA Earthdata and Data.gov), indicating recognized importance.
• Metadata includes specific product references ('pos', 'quat', 'tdp') for traceability.

Limitations

• No column names or row counts are provided by any source, obscuring the data's internal structure.
• License is ambiguously listed as 'other-license-specified' without further details.
• Sources disagree on freshness: one lists an update date of 2026-03-13, while another lists none, creating uncertainty.
