Hourly GPS tracking of the Sentinel-6A satellite

Sentinel-6A MF Jason-CS L1B GNSS-POD Tracking Data Hourly
deformation NASA POCLOUD Level 1B RINEX
In plain English

What it measures. Hourly satellite-positioning (GPS-style) tracking data showing exactly where the Sentinel-6A satellite was as it orbited.

How it's made. A Level-1B product from the GNSS-POD tracking system on the Sentinel-6A altimetry mission, recording precise orbit-tracking measurements every hour.

How & where you'd use it. Used to pin down the satellite's exact location, which is essential for turning its radar readings into accurate sea surface height; a technical support input rather than a science product on its own.
