The GBT Dynamic Scheduling System: An Update

Clark, Mark

The Robert C. Byrd Green Bank Telescope's (GBT) Dynamic Scheduling System (DSS), in production use since September 2009, was designed to maximize observing efficiency while not sacrificing telescope flexibility, data quality, or generate undue adversity for the observers. Using observing criteria, observer availability and qualifications, three-dimensional weather forecasts, and telescope state, the DSS software is capable of optimally scheduling observers 24 to 48 hours in advance on a telescope having a wide-range of capabilities in a geographical location with variable weather patterns. Recent improvements include an expanded frequency coverage (0.390-90 GHz), proper treatment of fully sampled array receivers and increasingly diverse observing criteria, accounting for atmospheric instability from clouds, and new tools for scheduling staff to control and interact with generated schedules and the underlying database.
