"During the early Cold War, outer space became a politically contested space, and changes in its spatial perception were related to political and ideological controversies. The article highlights the specific relevance of Euclidean geometry in representations of outer space. Focusing on illustrations and expositions in both postwar German States, it argues that shifts within the spatial imagination and representation of space corresponded with the first satellite missions and condensed debates about the future of technology and the moral legacies of the Second World War. In October 1957, Sputnik I, the first artificial satellite to orbit the Earth and a Soviet construction, urged engineers, scientists, and illustrators to find new ways of depicting and communicating the spaces of outer space to the public and to each other. For decades, space fiction had implicitly stifled theories on the relativity of space and time by hinting at traditional motifs of conquest through machines. Early spaceflight, however, was not about immediate flights to other planets, but about the orbit, a space without a traditional place, yet imagined as being of paramount importance for strategic superiority. Driven by political tensions and drawing on representations established in physics and astronomy, the first satellite projects were designed and explained as missions to places that needed to be defined and controlled because they were strange and new."

Applications of satellite communications has broader usage; for instance voice, video calling, internet, fax, television, and radio communications. There are abundant and various types of satellites that has applications from amplification of radio telecommunications to military applications and most importantly its application are globally and it also allows transmission of high amount of data.In this paper various types of advanced satellites are discussed; some of them are quantum communication through satellites, metamaterials for better satellite antennas, National Aeronautics and Space Administration's (NASA) laser communications, ZigBee based inter-satellite communications, quantum encryption network through satellite

Das von internationalen Autoren aus Wissenschaft und Praxis des Raumfahrtrechts verfasste Werk beschäftigt sich im Kern mit Problemen des Eigentumrechts an Satelliten, deren Übertragung und der Haftung bei Schäden.Darüber hinaus werden unter anderem die Registrierung von Raumobjekten unter UN-Rahmenbedingungen und die Zuweisung von Frequenzen behandelt.Die Publikation ist ein bedeutender Beitrag zur theoretischen Debatte über das Recht des Weltraums, ist aber zugleich ein wichtiges Instrument für die Anwaltschaft im Finanz- und Versicherungssektor

"Meteorological Satellite Systems" is a primer on weather satellites and their Earth applications. This book will review historic developments and recent technological advancements in GEO and polar orbiting meteorological satellites. It will explore the evolution of these remote sensing technologies and their capabilities to monitor short- and long-term changes in weather patterns in response to climate change. Satellites developed by various countries, such as U. S. meteorological satellites, EUMETSAT, and Russian, Chinese, Japanese and Indian satellite platforms are reviewed. This book also discusses international efforts to coordinate meteorological remote sensing data collection and sharing. This title provides a ready and quick reference for information about meteorological satellites. It serves as a useful tool for a broad audience that includes students, academics, private consultants, engineers, scientists, and teachers

An examination of satellite imagery as a tool for the humanitarian community points out the capability of satellite images to accurately pinpoint the location & state of displaced people or show how far a refugee camp is from international borders, potential natural hazard risks, & access to water or firewood. Current uses of satellite imagery are described, noting that the cost of this technology has fallen dramatically over the last few years, allowing it to easily fit into a humanitarian operations budget.
