ACE Weekly Report 01-09-02 All ACE spacecraft subsystems are performing nominally. Attitude maneuvers were successfully performed on 12/21/01 and 01/02/02. The next attitude maneuver is scheduled for 01/14/02. OCR CRIS-011 executed on 01-03-02 to turn on the image intensifier back on. It had been turned off during recent solar activity. OCR ULEIS-071 executed on 01-08-02 to increase the gain of the Start2 micro channel plate. ACE continues to experience degraded telemetry and command failures during its supports with Station D27. The ACE NOPE has been notified and an investigation is on going. Anomalies: 12/24/01 AR# G01-0134 MOC experienced degraded telemetry during the D27 support. Station notified. The RF Loop Bandwidth was increased from 100 to 300 Hz, improving the data quality for the remainder of the support. Numerous redumps performed to capture affected slices. One command was also retransmitted, most likely due to a bit flip in the acquisition sequence (DR#G100649). 12/29/01 AR# G01-0136 MOC experienced degraded telemetry throughout D27 support. Station notified. FOT informed that station had seen two drops which they believed to be the cause of the degraded telemetry. Insufficient time during the support to redump all of the affected slices. Remaining redumps will be performed during the following support. 01/01/02 AR# G02-0002 MOC experienced degraded telemetry throughout D27 support. Station notified. The RF Loop Bandwidth was increased from 100 to 300 Hz, slightly improving the data quality. Insufficient time during the support to redump all of the affected slices. Remaining redumps will be performed during the following support (DR #100666). 01/01/02 AR# G02-0003 One command transfer frame failure occurred during the support with D27. Command was retransmitted and verified by the spacecraft (DR# G100667). 01/02/02 AR# G02-0004 Two separate command transfer frame failures occurred during the support with D27 (DR# G-100669). Both commands were verified by the spacecraft.
