Current efforts to integrate multiple planning and scheduling subsystems into an end-to-end (scientist-observatory/spacecraft) planning system are ‘handcrafted’ and very resource intensive. In addition, future spacecraft/observatory configurations such as constellations and multi-observatory ‘campaigns’ introduce challenges that require a new approach to planning and scheduling system integration. The Advanced Architectures and Automation Branch of NASA’s Goddard Space Flight Center has embarked on a multi-year project entitled ComPASS (Common Planning And Scheduling System) with the goal of producing a common framework for end-to-end collaborative planning and scheduling. ComPASS is intended to streamline automation of the planning process and enable general application of automated collaborative planning technologies.
During NASA FY99, the initial project year, the ComPASS project has developed the infrastructure for plan distribution/collaboration, a prototype for common plan representation, and interfaces to existing components. The first set of components to be integrated include an extended version of Goddard’s Scientist’s Expert Assistant (SEA) for science client functionality, ASPEN - a planner/scheduler from the Jet Propulsion Laboratory (JPL), and Satellite Toolkit (STK) from Analytical Graphics, Inc.
This talk will concentrate on the ComPASS architecture and implementation approaches.
