== NOAA-20 Rephasing Maneuver Burn == | |||
* On March 20 17:20:45 to 17:23:56 NOAA-20 17:20:45 to 17:23:56performed a sequence of propulsive maneuvers as part of an orbit rephasing effort to provide 180 degree separation between NOAA-20 and NOAA-21. NOAA-20 was back in mission point at 17:40:34 UTC and drifted at a lower altitude, maintained until it is 180 degrees to NOAA-21. Rephasing NOAA-20 took approximately 15 days. During this time, NOAA-20 did not meet its orbit requirements and users should exercise caution when using the NOAA-20 science data. Any use of this data is undertaken at the user's own risk. During this period NOAA-20 ATMS and CrIS were turned off in FP. On April 04, 2024 11:56:00Z, NOAA-20 performed` a 110 second propulsive Re-Phasing Maneuver (RPH) to re-establish mission orbit.

== SNPP GPS geolocation problem May 25 2024. July 24 2024, Sep 24 2024, Nov 2 2024== | |||
* Starting on May 25 at ~22:30 UTC, the GPS on the S-NPP spacecraft toggled to invalid causing the geolocation of all observed data to be inaccurate and out of the mission specifications. Initially degradation was seen in VIIRS and science products were disabled at 17:00 UTC on May 28, 2024. S-NPP OMPS Limb Profile (LP) products disabled at 21:00 UTC on May 29th, 2024. Later due to increased degradation seen in all S-NPP science products, all S-NPP science products were disabled on PDA OPS at 16:00 UTC on May 30, 2024. [https://www.ospo.noaa.gov/data/messages/2024/05/MSG_20240530_1610.html NESDIS satellite message]. | |||
* Recovery efforts on the SNPP GPS unit were carried out and completed June 3 and the Cal/Val team confirmed that the GPS results are valid. Science data after 18:00 UTC June 4, 2024 will meet mission specifications. [https://www.ospo.noaa.gov/data/messages/2024/06/MSG_20240604_1805.html NESDIS satellite message] | |||
* There was another outage of SNPP instruments starting 24 July 2024. SNPP went into SAFE HOLD. Originally this was said to be due to a Command Data Processor (CDP) reset at 05:28 UTC 7/24 but then the message was corrected to say there were geolocation errors. Spacecraft recovery efforts were carried out and various instruments were placed in operational mode, but the data was held back from science customers until approved by the Cal/Val team. Data was unavailable in our input stream until 18z 7/30 2024. [https://www.ospo.noaa.gov/data/messages/2024/08/MSG_20240809_1426.html NESDIS satellite message] | |||
* Once again the geolocation for the S-NPP spacecraft entered a degraded state starting with the observation time of 22:44:05z on September 24, 2024. Operations was able to recover the S-NPP spacecraft to a valid geolocation state at 16:34 UTC on September 27, 2024. Cal/Val teams have confirmed that all S-NPP Science products are meeting mission specifications and ready for operational use. Science data were enabled at 19:30 UTC.

* Another geolocation failure was reported beginning Nov 2 2024 2215UTC. Operations recovered the S-NPP spacecraft to a valid geolocation state at ~17:20 UTC on November 6, 2024. S-NPP Science products were enabled at 16:30 UTC on November 8, 2024. [https://www.ospo.noaa.gov/data/messages/2024/11/MSG_20241108_1653.html NESDIS link] | |||
== NOAA-21 geolocation problem == | |||
* Starting on July 20 at ~06:18 UTC, the geolocation of the NOAA-21 spacecraft entered a degraded state causing the data to be inaccurate and out of mission specifications. Operations was able to recover the NOAA-21 spacecraft to a valid Geolocation state on July 20, 2024. [https://www.ospo.noaa.gov/data/messages/2024/07/MSG_20240720_2002.html A bulletin] issued 2002UTC stated the Cal/Val temas had confirmed the NOAA-21 Science products are ready for operational use. | |||
== AIRS Aqua outage 26-27 July 2024 == | |||
* AIRS data was unavailable in FP from 00z 26 July to its restart at 18z 27 July due to a scheduled calibration test. | |||
== S-NPP ATMS in Safe Hold 19 Nov 2024 == | |||
* Beginning November 6, 2024, the S-NPP ATMS telemetry showed elevated temperatures, currents, and voltages from the scan drive compensator motor. The OSPO JPSS Engineering team is in the process of diagnosing the issue and preparing mitigation measures. The ATMS instrument was placed into Safe Hold to prevent possible damage to the instrument scan drive compensator motor function. The ATMS instrument on the S-NPP satellite was placed in Safe Hold at 1630 Z on November 19, 2024 and will be offline until further notice.
