EUVE Daily Operations

The EUVE Science Operations Center (ESOC) at the Center for EUV Astrophysics in Berkeley, California, handles the day-to-day operations of the EUVE satellite and its instruments. These operations include receiving and archiving the telemetry data, and monitoring instrument health. The Center analyzes the engineering data to assess the health of the instruments and the validity of the scientific data. The ESOC stores all telemetry data received from the satellite in the Science Data Storage Facility.

Prior to EUVE's launch, the ESOC was used to provide remote support for all phases of the instrument integration and testing at GSFC, and prelaunch testing at the Kennedy Space Center.

During the survey portion of the mission, which occurred during the first six months of the mission, the ESOC generated preliminary sky maps, monitored instrument health and verified instrument performance.

Now, during the pointed Guest Observer phase of the mission, the ESOC makes preliminary spectra for evaluating data quality and schedules all spectroscopic observations.

The Science Operations Center is built around networked clusters of UNIX-based workstations and servers. These are operated by teams of scientists, students, payload controllers, and data aides. The Science Data Analysis Facility comprises high-capacity optical disk storage for archival purposes, and hard disks for high-speed access to data during processing.
