Date Time Component Description
07/1/2014 22:36:38 DSP1 Per request by CNES, performed A-DCS Partial Software Restart: Processing Software (DSP) Only
07/1/2014 22:36:38   Put A-DCS to Nominal Mode
02/7/2014 21:32:07 DSP1 Per request by CNES, performed A-DCS Partial Software Restart: Processing Software (DSP) Only
02/3/2014 00:00:00 DSP1 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.
07/11/2012 19:41:42 DSP1 Per request by CNES, performed A-DCS Partial Software Restart: Processing Software (DSP) Only
07/11/2012 09:42:44 DSP1 On July 11th, 2012 09:42:44 UTC a WATCHDOG_ERROR occurred on NOAA-19. CNES reported they were not recieving payload data.
08/04/2010 17:32:00 DSP1 Per request by CNES, performed A-DCS Full Software Restart
11/13/2009 19:14:00 TX1 Turned off TX1
10/15/2009 12:48:26 RX2 Executed start up of A-DCS on RX2 and TX1
10/15/2009 12:38:27 RX1 Turned off all RXs and TXs
10/10/2009 21:18:00 TX1 The 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
09/28/2009 20:30:50 TX1 Turns off A-DCS RX1 and TX1
09/28/2009 20:30:50 TX1 Turns on A-DCS RX1 and TX1
09/26/2009 18:40:00 TX1 Corruption 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.
09/03/2009 13:15:00 TX1 Turns on A-DCS RX1 and TX1
09/03/2009 13:00:00 TX1 Turns off A-DCS RXs and TXs
09/01/2009 12:00:00 TX1 CLS and CNES have observed a corruption of the Mission telemetrycaused by the FIFO component (as explained on Metop-A) and requires a hardware reset of the instrument.
05/18/2009 11:26:00 TX1 A-DCS XMTR 1 ON for testing
04/29/2009 19:24:00 TX2 Turn off of A-DCS TX2
04/27/2009 11:39:00 TX2 A-DCS Transmitter 2 turned on.
