Operations CXO Status Report

Friday 8 May 2020 9.00am EDT

During the last week Chandra completed the observing schedule as planned.

Real-time procedures were executed on May 7 to perform a routine self-check of the Electrical Interface Assembly (EIA) Sequencer and to perform a diagnostic dump of the Control Processing Electronics (CPE). A third real-time procedure was executed on May 8 to uplink two flight software patches. The first patch was to update the gyro calibration misalignment matrix and the second patch was to update the initialization values of the gyro bias vector. Additional real-time procedures were executed during each ground contact to reset the DSN Outage Dead Man Load.

The schedule of targets for the next week is shown below.
