“…The command and telemetry applications provide boilerplate mission management functionality, and the software bus enables the user to add more applications to interface with the system using a publish-subscribe mechanism. An additional benefit of cFE is its networking capabilities, which include several options such as the Software Bus Network (SBN) and more recently the Software Bus Distributed (SBD) [4]. cFE also works on top of the OSAL (Operating System Abstraction Layer), which enables cFE to work on Real-Time Operating Systems (RTOS) for missions requiring low jitter and determinism.…”

Autonomy in space systems can drastically reduce the workload of ground crews for satellite missions, especially for clusters of satellites. Additionally, autonomy can increase the efficiency of missions by maximizing the utilization of resources and rapidly handling any issues that arise without having to wait for instructions from the ground. This research presents an agentbased, task-execution approach to onboard spacecraft autonomy. Instead of the traditional approach requiring onboard planning and scheduling, this method uses a combination of constraint and priority parameters associated with every task to ensure robust task execution with behavior as intended. Using this method, tasks will only run under safe conditions (e.g. no conflict with any running tasks), which enables conflicting tasks to be scheduled closer together or even overlapping for lower-priority tasks. This approach manages the execution of tasks on the timescale of seconds, enabling conflicting tasks to run sequentially, thereby increasing productivity if earlier tasks finish ahead of schedule. This framework leverages the NASA-developed, open-source projects cFE and PLEXIL and was tested on development boards comparable to flight hardware.
