Ground-Based Global Navigation Satellite System (GNSS) GPS real-time POD Clock Corrections (1-second sampling, 60-second files) from NASA CDDIS

This product contains a high-rate 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.
