Global Navigation Satellite System Real-Time Clock Products

Daily satellite and receiver clock products derived from Global Navigation Satellite System (GNSS) data analysis. The dataset is generated by International GNSS Service (IGS) analysis centers and combined by the IGS analysis coordinator to form the official IGS real-time clock product, used for comparison purposes. It is hosted by NASA's Crustal Dynamics Data Information System (CDDIS).

Use Cases

• Comparing and validating real-time GNSS clock estimates from different analysis centers.
• Supporting high-precision real-time kinematic (RTK) positioning applications.
• Analyzing temporal stability and performance of satellite atomic clocks.
• Contributing to studies on Earth's crustal dynamics and reference frame maintenance.

Strengths

• Data is produced by the authoritative International GNSS Service (IGS) network.
• Products are generated daily, indicating regular updates.
• Cross-platform presence on NASA and U.S. government portals signals recognized importance.

Limitations

• No column names, row counts, or file sizes are provided by any source, limiting technical assessment.
• The license is ambiguously listed as 'other-license-specified' without details.
• The listed last update date of March 2026 is a future date, indicating a metadata conflict.
