Topic: Jason-3 maneuver scheduled for April 04, 2018

Date Issued: April 03, 2018 1531Z

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

Date/Time of Initial Impact: April 04, 2018 00:20:42Z

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 4-April-2018 starting at 00:20:42Z. There will be an expected change of +11.4 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.
