GPS tracking data for precise satellite position, hourly (Sentinel-6A)

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

What it measures. GPS-style tracking signals used to pin down exactly where the satellite is in its orbit, provided in hourly files.

How it's made. Collected by the GNSS receiver on the Sentinel-6A radar altimetry satellite as an early-stage tracking product.

How & where you'd use it. A behind-the-scenes input for calculating the satellite's precise position, which is essential for accurate sea-height measurements; rarely used on its own.
