System Design of the Miniaturized Distributed Occulter/Telescope (mDOT) Science Mission
This paper presents the results of a system design for the miniaturized distributed occulter/telescope (mDOT) science mission conducted by Stanford University and NASA Ames research center underExpand
Formation Design of Distributed Telescopes in Earth Orbit for Astrophysics Applications
This paper presents a new formation design that enables deployment of large distributed telescopes aligned with inertial targets in Earth orbit. To minimize propellant consumption, the proposed des...
Real-Time Algorithm for Globally Optimal Impulsive Control of Linear Time-Variant Systems
This paper addresses the problem of minimizing the cost of a set of impulsive control inputs subject to the constraint that a linear time-variant dynamical system reaches a desired state at aExpand
Safe spacecraft swarm deployment and acquisition in perturbed near-circular orbits subject to operational constraints
TLDR
The proposed deployment and formation acquisition procedures are validated through simulations using a high-fidelity numerical orbit propagator and demonstrate that the proposed procedures provide a means of safely initializing swarm formations at low delta-v cost in low earth orbit. Expand
AAS 16-530 IMPROVED MANEUVER-FREE APPROACH TO ANGLES-ONLY NAVIGATION FOR SPACE RENDEZVOUS
This work introduces a novel strategy for improving angles-only relative navigation for distributed space systems. Instead of relying on orbit or attitude maneuvers to reconcile the knownExpand
A dynamical characterization of internally-actuated microgravity mobility systems
TLDR
The results show that internally-actuated rovers, from an actuation standpoint, are a viable mobility solution for a vast class of small Solar System bodies. Expand
System design of a miniaturized distributed occulter/telescope for direct imaging of star vicinity
The Space Rendezvous Laboratory (SLAB) at Stanford is investigating the feasibility of a miniaturized distributed occulter/telescope system (mDOT) to directly image exozodiacal dust and JovianExpand
