Book Description
This document summarizes the results of a MITRE initiative to define a national strategy for navigation and timing. The Global Positioning System (GPS) currently provides the foundation for our nation’s navigation and timing. GPS's many attributes ensure that it will remain the foundation for decades to come. Yet reliance on GPS is excessive, especially since GPS and its uses are currently fragile, and threats continue to emerge and grow. In response, various alternative sources of position, velocity, and time (PVT) are being advocated, often without adequate assessment or planning for how they can cost-effectively meet future needs and address future threats. A national strategy is needed to efficiently and effectively focus scarce resources, defining a consistent, long-term way ahead. This document describes such a strategy.

Book Description
Space Security involves the use of space (in particular communication, navigation, earth observation, and electronic intelligence satellites) for military and security purposes on earth and also the maintenance of space (in particular the earth orbits) as safe and secure areas for conducting peaceful activities. The two aspects can be summarized as "space for security on earth" and “the safeguarding of space for peaceful endeavors.” The Handbook will provide a sophisticated, cutting-edge resource on the space security policy portfolio and the associated assets, assisting fellow members of the global space community and other interested policy-making and academic audiences in keeping abreast of the current and future directions of this vital dimension of international space policy. The debate on coordinated space security measures, including relevant 'Transparency and Confidence-Building Measures,' remains at a relatively early stage of development. The book offers a comprehensive description of the various components of space security and how these challenges are being addressed today. It will also provide a number of recommendations concerning how best to advance this space policy area, given the often competing objectives of the world's major space-faring nations. The critical role to be played by the United States and Europe as an intermediary and "middle diplomat" in promoting sustainable norms of behavior for space will likewise be highlighted. In providing a global and coherent analytical approach to space security today, the Handbook focuses on four areas that together define the entire space security area: policies, technologies, applications, and programs. This structure will assure the overall view of the subject from its political to its technical aspects. Internationally recognized experts in each of the above fields contribute, with their analytical synthesis assured by the section editors.

Book Description
The authors assess the costs associated with realistic threats to domestic, nonmilitary uses of the Global Positioning System (GPS), and consider possible additions to the positioning, navigation, and timing ecosystem in light of those costs.

Book Description
The proliferation of counterspace weapons across the globe often calls into question what can be done to best protect satellites from attack. This analysis from the CSIS Aerospace Security Project addresses different methods and technologies that can be used by the United States government, and others, to deter adversaries from attack. A wide range of active and passive defenses are available to protect space systems and the ground infrastructure they depend upon from different types of threats. This report captures a range of active and passive defenses that are theoretically possible and discusses the advantages and limitations of each. A group of technical space and national security experts supported the analysis by working through several plausible scenarios that explore a range of defenses that may be needed, concepts for employing different types of defenses, and how defensive actions in space may be perceived by others. These scenarios and the findings that resulted from subsequent conversations with experts are reported in the penultimate chapter of the report. Finally, the CSIS Aerospace Security Project team offers conclusions drawn from the analysis, actionable recommendations for policymakers, and additional research topics to be explored in future work.

Book Description
As U.S. service members deploy for extended periods on a repeated basis, their ability to cope with the stress of deployment may be challenged. Many programs are available to encourage and support psychological resilience among service members and families. However, little is known about these programs' effectiveness. This report reviews resilience literature and programs to identify evidence-informed factors for promoting resilience.

Book Description
China Satellite Navigation Conference (CSNC 2022) Proceedings presents selected research papers from CSNC 2022 held during 22nd-25th May, 2022 in Beijing, China. These papers discuss the technologies and applications of the Global Navigation Satellite System (GNSS), and the latest progress made in the China BeiDou System (BDS) especially. They are divided into 10 topics to match the corresponding sessions in CSNC2022 which broadly covered key topics in GNSS. Readers can learn about the BDS and keep abreast of the latest advances in GNSS techniques and applications.
