The objective of this paper is to investigate which approach would lead more reliable CubeSats: full subsystem redundancy or improved testing. Based on data from surveys, the reliability satellites and subsystems estimated using a Kaplan–Meier estimator. Subsequently, variety models defined their maximum likelihood estimates are compared. A product Lognormal distribution addressing immaturity failure Gompertz wear-out found best represent CubeSat reliability. Bayesian inference used find...
The Earth-Moon system is constantly bombarded by meteoroids of different size and impact speed. Observation the impacts on Moon can enable thorough characterization Lunar meteoroid flux, which similar to that Earth. While Earth-based observations are restricted weather, geometric illumination conditions, a Lunar-based observation campaign improve detection rate and, when observing far side, complement in both space time taken from Meteoroid Impact Observer (LUMIO), one two winning concepts...
The estimation of the relative pose an inactive spacecraft by active servicer is a critical task for close-proximity operations, such as In-Orbit Servicing and Active Debris Removal. Among all challenges, lack available space images satellite makes on-ground validation current monocular camera-based navigation systems challenging task, mostly due to fact that standard Image Processing (IP) algorithms, which are usually tested on synthetic images, tend fail when implemented in orbit. In...
