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

Details/Specifics of Change: 

Jason-3's LRO ground track is being shifted -4km June 22-26, 2026 where it will remain until July of 2027. It will be accomplished with multiple maneuvers.
The second maneuver will consist of two thrusts. 
The 1st thrust is scheduled for 25-June-2026 starting at 23:27:24 Z with an expected decrease of around 139 m in the semi-major axis.
The 2nd thrust is scheduled for 26-June-2026 starting at 02:15:13 Z with an expected decrease of around 139 m 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.
