Trajectory Planning for Spacecraft Rendezvous with On / Off Thrusters
(Elsevier, 2011)
The objective of this work is to present a trajectory planning algorithm for spacecraft rendezvous that is able to incorporate Pulse-Width Modulated (PWM) control signals. The algorithm is based on linearization around a ...

Conflict Resolution with Time Constraints in Trajectory-Based Arrival Management
(SESAR Joint Undertaking, 2012-11)
The meet-time problem in arrival management is analyzed, that is, the problem of generating conflict-free tra- jectories that meet the scheduled times of arrival. The conflict- resolution algorithms developed are based ...

A Symmetry-Based Unscented Particle Filter for State Estimation of a Ballistic Vehicle
(Elsevier, 2023)
The problem of state estimation for vehicles when an initial fix is highly uncertain and/or the number of sensors is not sufficient (and changes with time) is very relevant for both aircraft and spacecraft navigation. This ...
