Date Issued: November 25, 2025 1809Z

Product(s) or Data Impacted:Jason-3 Operational Geophysical Data Records (OGDRs)

Date/Time of Expected End: TBD

Length of Event: Any impact to products would be 30 minutes before and up to 2 hours following the maneuver.

Details/Specifics of Change: A Jason-3 maneuver is scheduled for 27-November-2025 starting at  02:06:42 Z. There will be an expected increase of around 13.8m in the semi-major axis, possibly resulting in large radial orbit errors in the OGDRs. Over any ocean points, this will affect the sea surface height, but not the wind and wave content in the products.
