Ground-Based Global Navigation Satellite System (GNSS) Guardian GPS daily accumulated real-time POD Clock Corrections (60-second sampling, 24-hour files) from NASA CDDIS

Metadata Updated: December 7, 2023

This product contains a time series of clock biases for healthy satellites in the GPS constellation that are accumulated every minute throughout the day. In addition, formal 1-sigma uncertainties for the corrections are provided. The product is generated at JPL's Global Differential GPS Operations Centers in real-time. The data in this product can be concatenated with other daily products to provide larger coverage in time.
