An Architectural Pattern for Goal-Based Control
ABSTRACT -
Time-based command sequencing is the time-honored paradigm for control of spacecraft and rovers in NASA's robotic missions, but the paradigm has been increasingly strained to accommodate today's miss ...

State-Based Models for Planning and Execution
ABSTRACT - Many traditional planners are build on top of existing execution engines that were not necessarily intended to be
operated by a planner. The Mission Data System has been designed from the onset to ha ...
