Date/Time Issued: July 1, 2021 2352Z
Product(s) or Data Impacted: All NOAA 20 OMPS products
Date/Time of Initial Impact: July 1, 2021 1720Z
Date/Time of Expected End: July 1, 2021 18
Length of Outage: 1 Hour, 37 Mins
Details/Specifics of Change: During NOAA20 SVL 18747 (AOS 171149z), a loss of telemetry occurred during the support which led to a delay in the upload of the weekly OMPS daily activity schedule. As a result, the OMPS instrument daily activity schedule (command stored memory) was not reactivated before the loss of signal and remained off for one orbit. This resulted in a loss of NOAA20 OMPS data that is unrecoverable. The OMPS instrument daily activity schedule command stored memory was activated/restarted to normal as soon as contact was established on NOAA-20 SVL 18748 (AOS 185459Z) contact.
