Reconfigurable topologies for decentralized control of spacecraft formations in Deep Space
This paper discusses control and communication topologies that asynchronously distribute the sensing, communication and computation tasks amongst the spacecraft in the formation. Our approach allows the dynamic reconfiguration of the measurement and communication topologies while maintaining the specified formation performance objectives. An illustrative simulation example is presented.

Decentralized and Asynchronous Planning for Cooperative Practices in High Altitude Digitally Enabled Operations
Cooperative practices will likely be foundational to future digitally enabled airspace operations characterized by decentralized and asynchronous decision-making. This paper explores the implementation of cooperative practices in high-altitude airspace. The digitally enabled operations framework, under exploratory investigation by NASA as a potential new operating mode, which is enabled and dependent on digital technologies and information sharing, may create new operational possibilities for a wide range of vehicle types and missions. An essential element of the operating mode framework under investigation, cooperative practices, could empower operators to manage critical functions such as deconfliction, equitable airspace usage, and demand-capacity balancing. The use of cooperative practices would involve asynchronous flight information sharing and decentralized conflict management by operators, representing a major change from traditional air traffic services that use synchronous surveillance information to support centralized decision-making by air traffic controllers. This paper details three key components for implementing cooperative practices for decentralized, digitally enabled operations: (a) intent modeling and sharing, (b) conflict detection, and (c) cooperative deconfliction.
