Automated System Identification for Satellite Attitude Control
A novel approach to on-obit system identification of satellite attitude control dynamics is presented. The approach is fully automated and will thus enable a variety of satellite applications, including high-performance proliferated constellations and modular payloads. The key enabling feature of the approach is the ability to estimate the uncertainty in the model and then perform additional data collections specifically to reduce the uncertainty. A prototype software implementation of the algorithm accurately estimated multiple structural modes in a CubeSat simulation and a CubeSat reaction wheel testbed in preparation for an on-orbit demonstration as part of the The Aerospace Corporation’s Slingshot 1 mission

Understanding Quantum Technologies 2022
Understanding Quantum Technologies 2022 is a creative-commons ebook that
provides a unique 360 degrees overview of quantum technologies from science and
technology to geopolitical and societal issues. It covers quantum physics
history, quantum physics 101, gate-based quantum computing, quantum computing
engineering (including quantum error corrections and quantum computing
energetics), quantum computing hardware (all qubit types, including quantum
annealing and quantum simulation paradigms, history, science, research,
implementation and vendors), quantum enabling technologies (cryogenics, control
electronics, photonics, components fabs, raw materials), quantum computing
algorithms, software development tools and use cases, unconventional computing
(potential alternatives to quantum and classical computing), quantum
telecommunications and cryptography, quantum sensing, quantum technologies
around the world, quantum technologies societal impact and even quantum fake
sciences. The main audience are computer science engineers, developers and IT
specialists as well as quantum scientists and students who want to acquire a
global view of how quantum technologies work, and particularly quantum
computing. This version is an extensive update to the 2021 edition published in
October 2021.Comment: 1132 pages, 920 figures, Letter forma
