Bandyopadhyay, Saptarshi; Gehlot, Vinod; Balas, Mark; Bayard, David S.; Quadrelli, Marco B., 2020, "Detection and Mitigation of Transient Instabilities in Multi-Agent Systems and Swarms", https://hdl.handle.net/2014/53262, VIRTUAL The International Symposium on Artificial Intelligence, Robotics and Automation in Space (i-SAIRAS) 2020, Pasadena, California, October 19-23, 2020, JPL Open Repository
We first introduce the novel concept of transient instabilities in multi-agent systems and swarms, i.e., a small disturbance leads to increasing-amplitude oscillations throughout the swarm, which results in a large number of inter-agent collisions. This instability is dominant in... |

Quadrelli, Marco M; Gelot, Vinod P.; Balas, Mark J.; Bandyopadhyay, Saptarshi; Quadrelli, Marco B.; Bayard, David S., 2020, "Projection-Based Inter-Agent Collision Avoidance in Dual Agent Systems", https://hdl.handle.net/2014/53071, The Sixteenth International Conference on Autonomic and Autonomous Systems ICAS 2020, Lisbon, Portugal, September 27 - October 1, 2020, JPL Open Repository
Inter-agent collisions can occur in otherwise dynamically-stable (i.e., Lyapunov stable) dual-agent leaderfollower systems. These inter-agent collisions between the leader and the follower happen during the transient phase of the system’s evolution, although the steady-state beha... |

Rossi, Federico; Bandyopadhyay, Saptarshi; Mote, Mark; Croix, Jean-Pierre de la; Rahmani, Amir, 2020, "Communication-Aware Orbit Design for Small Spacecraft Swarms around Small Bodies", https://hdl.handle.net/2014/53211, 2020 AAS/AIAA Astrodynamics Specialist Conference, South Lake Tahoe, California, August 9-13, 2020, JPL Open Repository
Exploration of small Solar System bodies has traditionally been performed by single monolithic spacecraft carrying a number of science instruments. However, science instruments typically cannot be operated simultaneously due to the instrument requirements including optimal viewin... |

Quadrelli, Marco M; Vilnrotter, Victor; Hodges, Richard; Bandyopadhyay, Saptarshi; Finley, Susan; Kahan, Daniel, 2020, "Experimental Validation of Swarm Array Results Using Mars Cube One (Marco) A,B Downlink Signals", https://hdl.handle.net/2014/51154, 2020 IEEE Aerospace Conference, Big Sky, Montana, March 7-14, 2020, JPL Open Repository
In this paper, we investigate the feasibility of calibrating an orbiting phased array composed of CubeSat class spacecraft together with a larger reference (or “chief”) spacecraft, comprising an overall Swarm Array. Considered as an analog to the Deep Space Network (DSN) Uplink A... |

Villa, Jacopo; Bandyopadhyay, Saptarshi; Morrell, Benjamin; Hockman, Benjamin; Lubey, Daniel; Harvard, Alexei; Chung, Soon-Jo; Bhaskaran, Shyam; Nesnas, Issa A., 2020, "Optical Navigation for Autonomous Approach of Small Unknown Bodies", https://hdl.handle.net/2014/52356, 43rd Annual AAS Guidance, Navigation and Control Conference 2020, Breckenridge, Colorado, January 30 - February 5, 2020, JPL Open Repository
State of the practice in navigation around small celestial bodies heavily relies on ground sup- port and human skill, in particular, for perception-based operations such as optical navigation and mapping. This leads to longer duration and more complex mission operations and sub-... |

Gehlot, Vinod P.; Balas, Mark J.; Bandyopadhyay, Saptarshi, 2020, "Dynamic Stability And Adaptive Control of Networked Evolving Formations with Weak Nonlinearities", https://hdl.handle.net/2014/52287, AIAA Science and Technology Forum and Exposition (AIAA SciTech 2020), Orlando, Florida, January 06, 2020, JPL Open Repository
The dynamic stability of formation geometry is vital to the design of large scale multiagent systems. In this paper, we probe into the structure of the formation system matrix using the Laplacian of a digraph to develop several fundamental theoretical results on the stability of... |
