SWOT Level 1 Onboard Tracking Data from Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS)

Published by Jet Propulsion Laboratory;NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 02:02 PM | Dataset Last Updated: June 23, 2026
Tracking data measurements from the Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) payload receiver onboard SWOT. The tracking data are generated using signals from DORIS ground beacons and are used to perform precise orbit determination of the SWOT spacecraft. They are also used to compute the precise orbit ephemeris (POE), and the medium-accuracy orbit ephemeris (MOE) used for SWOT data processing. Distributed as one file per day in RINEX file format, available with latency of < 2 days.
