Update #1 (Final Update): The NOAA POES IJPS team coordinated with EUMETSAT to successfully command the S13 SARP instrument to reset at 1607Z. The USMCC used an in-house technique to generate new TCAL based on the commanding time reported by EUMETSAT via email. At 1702Z the USMCC sent the new TCAL to all US LEOLUTs and by 2104Z US LEOLUTs were reporting accurate data for S13.

Topic: SARSAT S13 (METOP-B/M1) LEO Satellite Search And Rescue Processor (SARP) Anomaly

Date/Time Issued: March 12, 2021 2251Z

Product(s) or Data Impacted: SARSAT alert data

Date/Time of Initial Impact: March 12, 2021 0103Z

Date/Time of Expected End: March 12, 2021 2104Z

Length of Outage: 20 hours, 1 minute

Details/Specifics of Change: The SARSAT Satellite S13 (METOP B/M1) has suffered an anomaly on the SARP instrument. The anomaly was detected based on no data on SARP since March 12 at 0103 UTC. The USMCC requested FMCC work with EUMETSAT to issue a SARP reset command. The USMCC is currently filtering all S13 SARP data until a recalculated time calibration (TCAL) is received.

Impact: Medium-Loss of Storage/forward capability. The satellite is limited to real-time/local distress detection and relay. Timeliness of global coverage detection and relay affected.
