Abstract:

In this system demonstration we present at set of tools being developed at NASA Jet Propulsion Laboratory
to support the next generation of operations of autonomous spacecrafts, specifically those capable of performing onboard planning and scheduling. We will focus on demonstrating two critical tools, Task Network Editor and Plan Reconstruction, that represent key functions in the uplink and downlink processes. In the uplink process, the Task Network Editor supports the knowledge engineering process of capturing intent/goals from engineers, scientists, and operators to be sent to the spacecraft. In the downlink process, the Plan Reconstruction tool supports the understating the decisions made by the onboard planner and the execution status. These tools have been integrated to an autonomy testbed, called MASCOT, to study the interaction between ground and onboard planning, as well as to assess/characterize the planner's performance running in different processors and hardware settings.
