Topic: Jason-3 maneuver February 4, 2025

 

Date Issued: Issued January 31, 2025 - 1923Z

 

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

 

Date/Time of Initial Impact: February 4, 2025 0138Z


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 maneuver is scheduled for 4-February-2025 starting at 01:38:38Z. There will be an expected decrease of around 9m 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.
