The NOAA-20 satellite successfully underwent a rephasing maneuver between March 20, 2024 - April 4, 2024, as part of an orbit rephasing to provide 180 degrees of separation between NOAA-20 and NOAA-21. This maneuver impacted the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NOAA-20. The Satellite remained in Mission Pointing Mode during the drift period which lasted for 16 days. The first propulsive burn maneuver successfully completed on March 20th, 2024, and lowered the NOAA-20’s altitude to a lower orbit. The satellite drifted for 16 days until positioned to 180 degrees from NOAA-21, after which another propulsive burn was performed successfully on April 4th, 2024, to raise the satellite back to its nominal orbit.

LandSIPS processing of all NOAA-20/J1 Land Science products was suspended for the duration of the maneuver, pending assessment by the VIIRS instrument Calibration and QA teams. All such processing has now been resumed, following approval by all concerned teams, and all processing and data dissemination are expected to be nominal from here onwards. For more details regarding this, please consult the LDOPE website.
