Object correlation, maneuver detection, and maneuver characterization are persistent
problems in space surveillance and space object catalog maintenance. This paper …

We investigate the pursuit-evasion differential game (PE Game) for satellites with continuous
thrust from the viewpoint of reachable domain (RD). A concept of hyper-reachable domain …

Continuous-thrust relative reachable set is presented for the spacecraft linear relative motion
near elliptical orbits. Two cases with different constraints are considered: the energy …

Reachable and controllable sets for electric propulsion spacecraft are important to many
problems including: dynamic replanning, robust mission design, space situational …

For spacecraft in formation flight, the knowledge on a reachable set for their relative motion
is crucial as it can be used to 1) assess their operational capability and plan tasks …

LOW-THRUST trajectory optimization, as a specialization of the optimal control problem, has
always been a challenge for no analytical solution exists. Many numerical methods are …

This work is concerned with the problem of reachable set synthesis for a class of singular
systems with time-varying delay via the adaptive event-triggered scheme. Compared with …

The conventional reachable domain problem for satellites with a single impulse under the
ideal two-body dynamical environment was extended to a more realistic scenario that takes …

For spacecraft formation flight, the information of relative motion reachable set is very
important, which can be used to predict the operating boundary of adjacent spacecraft and …

Reachable sets are sets of position states that the spacecraft can reach from its initial state
under mass and time constraints. In this study, a method to solve the reachable set of …
