Abstract: The optimization of the trajectory between a chaser spacecraft and a target object has been an area of research for the past few decades. In particular, real-time trajectory optimization is of particular interest as many of the current methods must be done offline and require a significant amount of time and/or processing power. One possible real-time suboptimal guidance strategy is the IDVD-SGRA strategy which combines a direct method (Inverse Dynamics in the Virtual Domain) and a nonlinear programming solver (Sequential Gradient-Restoration Algorithm) to produce suboptimal trajectories for proximity manoeuvres. This seminar will present an implementation of the IDVD-SGRA strategy, as well as demonstrate its robustness and ability to deal with uncooperative targets and obstacles.

Abstract: The continual accumulation of debris in Low Earth Orbits poses an increasing risk of future collisions, which have the capability of cascading beyond human control and rendering orbits unusable. As such, developing methods to actively remove debris is a key area of ongoing research. This presentation presents the work being done using a novel tether design for net and harpoon-based debris capture scenarios. The novel tether was previously experimentally validated in post-capture scenarios by Hovell and Ulrich (2017), whereas current work focuses on the deployment and capture phases of orbital debris removal.
