The collision probability computation of space objects plays an important role in space
situational awareness, particularly for conjunction assessment and collision avoidance …

This article proposes a low-thrust reconfiguration strategy for formation flying based on the
Jordan normal form and evaluates its performance based on the required control …

Autonomous underwater vehicles (AUVs) are increasingly being used for underwater survey
and exploration missions. The expanding mission scope for AUVs highlights the need for a …

This paper proposes an optimal control-based method named the rapid-Gauss
pseudospectral method (RGPM) to obtain a smooth time-optimal path for unmanned surface …

This article investigates a distributed game strategy for formation control of multispacecraft
subjected to nonlinear dynamics and J 2 perturbations. In the proposed problem, each …

This paper presents the development and analysis of a spacecraft formation flying
architecture. The desired state of each spacecraft is maintained using a model predictive …

This paper focuses on the issue of minimum-fuel rendezvous between an active chaser
satellite with continuousthrust capability and a passive target satellite. It is first formalized as …

In satellite formation missions, conventional low-thrust spacecraft need to continuously
consume fuel to maintain a stable formation configuration, which limits the mission period …

To rapidly design three dimensional low-thrust safe trajectories for spacecraft orbit transfer
and rendezvous problems, an analytic shape-based approach is proposed. Unlike some …

In this study, a fast costate estimation method derived from the Bezier-curve-based shaping
approach is proposed for indirect low-thrust transfer trajectory optimization. The trajectory is …
