Autonomous Navigation and Station-Keeping on Near-Rectilinear Halo Orbits
Yuri Shimane, Karl Berntorp, Stefano Di Cairano +1
This article develops an optical navigation (OPNAV) and station-keeping pipeline for the near-rectilinear halo orbit (NRHO) in high-fidelity ephemeris model dynamics, using synthet…
A practical guide to implementing zero-order-hold interplanetary trajectory legs
Dario Izzo, Harry Holt, Giacomo Acciarini +2
We study the practical implementation of zero-order-hold (ZOH) transcriptions for spacecraft trajectory optimisation, identifying a set of design principles that render them robust…
Optimization-Based Formation Flight on Libration Point Orbits
Yuri Shimane, Purnanand Elango, Avishai Weiss
A model predictive control (MPC) framework is developed for station-keeping in spacecraft formation flight along libration point orbits. At each control period, the MPC policy solv…
Revolution-Spaced Output-Feedback Model Predictive Control for Station Keeping on Near-Rectilinear Halo Orbits
Yuri Shimane, Stefano Di Cairano, Koki Ho +1
We develop a model predictive control (MPC) policy for station keeping on a Near-Rectilinear Halo Orbit (NRHO). The proposed policy achieves full-state tracking of a reference NRHO…
Multi-Vehicle Guidance for Formation Flight on Libration Point Orbits
Yuri Shimane, Purnanand Elango, Avishai Weiss
The multiple spacecraft guidance problem for proximity flight in libration point orbit is considered. A nonlinear optimal control problem with continuous-time path constraints enfo…
Cislunar Space Situational Awareness Constellation Design and Planning with Facility Location Problem
Yuri Shimane, Kento Tomita, Koki Ho
Driven by the surmounting interest for dedicated infrastructure in cislunar space, this work considers the satellite constellation design for cislunar space situational awareness (…
