“…Another mission, called Three Corner Sat (3CS) [8], was launched in 2002. The onboard autonomous system [9] used the Spacecraft Command Language (SCL) robust execution system, the CASPER planning system, the SELective MONitoring system (SELMON), and a satellites formation flying coordination package. NASA launched several space missions consisting of multi-satellite systems.…”

This paper presents an onboard autonomous mission re-planning system for Multi-Satellites System (MSS) to perform onboard re-planing in disruptive situations. The proposed replanning system can deal with different potential emergency situations. This paper uses Multi-Objective Hybrid Dynamic Mutation Genetic Algorithm (MO-HDM GA) combined with re-planning techniques as the core algorithm. The Cyclically Re-planning Method (CRM) and the Near Real-time Re-planning Method (NRRM) are developed to meet different mission requirements. Simulations results show that both methods can provide feasible re-planning sequences under unforeseen situations. The comparisons illustrate that using the CRM is average 20% faster than the NRRM on computation time. However, by using the NRRM more raw data can be observed and transmitted than using the CRM within the same period. The usability of this onboard re-planning system is not limited to multisatellite system. Other mission planning and re-planning problems related to autonomous multiple vehicles with similar demands are also applicable.

Safety and Security in Multiagent Systems

We are interested in developing multi-agent systems that can provide real-time performance guarantees for critical missions that require cooperation. In particular, we are developing methods for teams of CIRCA agents to build coordinated plans that include explicit runtime communications to support distributed realtime reactivity to the environment. These teams can build plans in which different agents use their unique capabilities to guarantee that the team will respond in a coordinated fashion to mission-critical events. By reasoning explicitly about different agent roles, the agents can identify what communications must be exchanged in different situations. And, by reasoning explicitly about domain deadlines and communication time, the agents can build reactive plans that provide end-to-end performance guarantees spanning multiagent teams.

“…As one of the trends in the future satellite networks, distributed satellite cluster network (DSCN) recently has drawn more and more attention. Many distributed satellite clusters (DSCs) have been deployed by some demonstrations, such as F6 (Future, Fast, Flexible, Fractionated, Free-Flying) Program, Techsat-21, and 3CSat (Three-Corner Satellite) [1][2][3]. DSC refers to a number of satellites that distribute on the same or adjacent orbit position.…”

Network architecture analysis is a curial issue for a large scale Machine-To-Machine (M2M) network. Considering an M2M backbone network which consists of distributed satellite clusters in geosynchronous orbit (GEO), a new distributed satellite cluster network (DSCN) hybrid topology architecture is proposed in this paper. To the best of the authors' knowledge, the conceptions of domains, strong/weak link, hubs, small world, and degree realizability are proposed for the first time in the DSCN based M2M backbone networks. How these features affect the network is given through analysis and simulation. By employing Network Science Theory, a strong constraint DSCN topology is presented. In addition, we compare the DSCN with several typical network topologies. Results show that the proposed hybrid architecture realizes a stunning trade-off between the efficiency and robustness.
