Topic: Jason-3 maneuver July 23, 2020


Date Issued: Issued July 21, 2020 - 1540Z


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

Date/Time of Initial Impact: July 23, 2020 21:24Z
   

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 23-July-2020 starting at 21:24Z. There will be an expected change of +8.75 m 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.
