Download or read book Handbook of Small Satellites written by Joseph N. Pelton and published by Springer. This book was released on 2020-09-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, the field of small satellites has expanded the space industry in a powerful way. Hundreds, indeed thousands, of these innovative and highly cost-efficient satellites are now being launched from Earth to establish low-cost space systems. These smallsats are engaged in experiments and prototype testing, communications services, data relay, internet access, remote sensing, defense and security related services, and more. Some of these systems are quite small and are simple student experiments, while others in commercial constellations are employing state-of-the-art technologies to deliver fast and accurate services. This handbook provides a comprehensive overview of this exciting new field. It covers the technology, applications and services, design and manufacture, launch arrangements, ground systems, and economic and regulatory arrangements surrounding small satellites. The diversity of approach in recent years has allowed for rapid innovation and economic breakthroughs to proceed at a pace that seems only to be speeding up. In this reference work, readers will find information pertaining to all aspects of the small satellite industry, written by a host of international experts in the field.

Download or read book The Urgent Need for Regulation of Satellite Mega constellations in Outer Space written by Scott Millwood and published by Springer Nature. This book was released on 2023-02-21 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book calls for the urgent regulation of satellite mega-constellations in outer space, proposing a new model of “international regulatory coordination”, in order to ensure the sustainable balance of science and advanced telecommunications. We are currently witnessing expansion of the Internet off our planet. The proliferation of new space-based internet connectivity has been accompanied by much discussion about the potential impact on astronomy. Scientists are increasingly concerned that mega-constellations proposed by SpaceX, OneWeb, Amazon and Facebook, might wreak havoc on scientific research and transform our view of the stars. These commercial operators plan to launch hundreds of thousands of satellites into Low-Earth Orbit (LEO) in the coming decade, representing a 1000% increase on objects currently in orbit. This book examines this new space race in the context of historical rivalries, for it is clear that mega-constellations are being actively pursued by a US administration determined to dominate LEO as tensions with China rise. This creates a risk of interference with earth-based scientific activities that use optical and radio frequency techniques to study the universe. This book examines these developments in the context of the Outer Space Treaty (OST), which provides all States with the freedom of scientific investigation, exploration and use of outer space, while balancing this with obligations to avoid interference with the space activities of other States. It draws upon interviews with some of Europe’s leading astronomers in order to highlight the extent to which the issue will require legal and regulatory reform of mega-constellation licensing processes, to ensure the integrity of astronomical science is preserved. The race to dominate LEO also comes at a time when the monopolistic power of Facebook, Amazon and other TechGiants, is under renewed scrutiny in western democracies. The author argues that a new governance framework for launch and operational licenses is urgently required, in which impact risk assessments, scale and proportionality, and stakeholder consultation processes should play important roles. It is now vital that the astronomical community – whose skill-set does not generally involve leading regulatory strategies – engage with those who can support its leadership in exerting a renewed influence. The diplomacy of science, which played a vital role during the Cold War and the establishment of global commons, must be reinvigorated for the New Space era..

Download or read book Orbital Debris written by National Research Council and published by National Academies Press. This book was released on 1995-07-07 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.

Available in PDF, EPUB and Kindle. Book excerpt: "The smallsat and mega-constellation industry is poised to place more smallsats (those with a mass less than 600 kg) in space in the next decade than all the satellites launched since the beginning of the space race. As advances in technology have made the use of space more feasible and economical, the number of smallsats in outer space has increased at an exponential rate. Technology miniaturization has also affected satellite technology and has allowed for the space industry to use smallsats with capabilities that only a few years ago would have required much larger satellites. These smallsats make possible the recent launch and proposal for mega-constellations (networks of over 100 satellites operating together) in Low Earth Orbit (LEO). The United States National Security Space Strategy recognizes that space operations are of vital importance to US national security For the United States Department of Defense, and militaries across the globe, these proposed mega-constellations provide both the potential for un-matched advantages over current architecture, but also numerous potential risks to national security. This thesis examines publicly available, unclassified documents, news articles, journals, publications, governmental reports, international treaties, laws and regulations, and other information to assess the current state of the smallsat and mega-constellation industry, as well as the trends going into the future. Using this information, compared with U.S. space policy and legal documents and the known threats to space systems, this thesis then considers how an increase in smallsats and mega-constellations benefits and threatens the United States National Security and whether current regulations are sufficient to address these changes. Some of the legal aspects discussed relate to space activities that include space situational awareness; cyber-security, intelligence, reconnaissance, and surveillance, on-orbit spying, radio interference, space debris, anti-satellite weapons, and space mines, to name a few"--
