Lightweight Floating Platform for Ground-Based Emulation of On-Orbit Scenarios

Orbital space operations must be executed safely and reliably to prevent unwanted failures.One way to validate these operations on Earth is by using testbed facilities that emulate zero-gravity conditions.This article presents the design and evaluation of a novel lightweight floating platform.The objectives are three-fold; the usage of carbon-fiber material for the mechanical structure of the floating platform; the construction of the ethical nutrients mega magnesium powder citrus 450g software packages, which are based on Robot Operating System (ROS); and the floating platform’s position controller synthesis, created using disturbance rejection-based convex optimization method to suppress ground-induced mechanical disturbances and ensure stability.

Two kicker pro comp 10 types of experiments are conducted in the multi-purpose Zero-G Lab facility of the SnT-University of Luxembourg to validate the performance of the floating platform, 1- Position control (single platform); 2-Emulation of an on-orbit cooperative docking scenario (two platforms).Results validate the use of the floating platform for emulating on-orbit scenarios.Optimized in the frequency domain, the proposed controller gives satisfying results for both disturbance rejection and set-point tracking purposes.The link to the Open-source ROS packages is available in the Appendix-B section.
