Date Time Component Description
02/07/201421:32:07DSP1Per request by CNES, performed A-DCS Partial Software Restart: Processing Software (DSP) Only
02/03/201412:00:00 As reporeted by CNES: Instrument not receiveing high data rate messages. Probable cause is a SEU iinducing multiple bit errors within RAM of signal processing board, uncorrectable by EDAC.As requested by CNES, executed ADSWRST CP to perform full reset of A-DCS instrument. Executed sucessfully with telemetry restored. See SCR #1205.
07/11/201219:41:42DSP1Per request by CNES, performed A-DCS Partial Software Restart: Processing Software (DSP) Only
07/11/201209:42:44DSP1On July 11th, 2012 09:42:44 UTC a WATCHDOG_ERROR occurred on NOAA-19. CNES reported they were not recieving payload data.
08/04/201017:32:00DSP1Per request by CNES, performed A-DCS Full Software Restart
11/13/200919:14:00TX1Turned off TX1
10/15/200912:48:26RX2Executed start up of A-DCS on RX2 and TX1
10/15/200912:38:27RX1Turns off all RXs and TXs
10/10/200921:18:00TX1The anomaly concerning the corruption of the A-DCS mission telemetry occured a third time on Saturday October 10 around 21:18 Z . Fixed by a reset of the FIFO read/write pointers; operating now on RX2 and TX1
10/10/200921:18:00RX2The anomaly concerning the corruption of the A-DCS mission telemetry occured a third time on Saturday October 10 around 21:18 Z . Fixed by a reset of the FIFO read/write pointers; operating now on RX2 and TX1
09/28/200920:30:50TX1Turns off A-DCS RX1 and TX1
09/28/200920:30:50TX1Turns on A-DCS RX1 and TX1
09/26/200918:40:00TX1Corruption of the A-DCS mission telemetry with a signature identical to the one on Sept. 1st caused by a failure of the output FIFO component, fixed by a reset of the FIFO read/write pointers.
09/03/200913:15:00TX1Turns on A-DCS RX1 and TX1
09/03/200913:00:00TX1Turns off A-DCS RXs and TXs
09/01/200912:00:00TX1CLS and CNES have observed a corruption of the Mission telemetrycaused by the FIFO component (asexplained on Metop-A) and requires a hardware reset of the instrument.
