Topic: Jason-3 maneuvers Scheduled for June 25, 2025

Date/Time Issued: June 25, 2025 1328Z

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

Date/Time of Initial Impact: June 25, 2025 17:46:51 Z

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: A Jason-3 collision risk mitigation maneuver and station keeping maneuver are being combined and will be executed in two burns today.

The first maneuver will start at 17:46:51 Z with an expected decrease of -125m in the semi-major axis.
The second maneuver will start at 19:38:42 Z with an expected increase of +120m in the semi-major axis.

The maneuvers may result 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.
