Northrop Grumman Australia will partner with Inmarsat to develop an agile, resilient and sovereign satellite communications capability to support the future

Auf dem Gebiet der Nachrichtensatelliten hat sich eine ungewöhnlich steile Entwicklung vollzogen. Erst 15 Jahre ist es her, seitdem der er ste geostationäre Nachrichtensatellit mit einer maximalen Kapazität von damals nur 240 Fernsprechkanälen gestartet wurde, und inzwischen ist die Technik so weit fortgeschritten, dass der in Bälde den Betrieb aufnehmende neueste Typ, INTELSAT V, bereits 12 000 Fernsprechsignale und 2 Fernsehprogramme gleichzeitig übertragen kann. In Zukunft werden Nachrichtensatelliten mit noch grösserer Leistung, scharf bündelnden Antennen, hoher Ausrichtgenauigkeit und flexiblen Möglichkeiten des Vielfachzugriffs die Erde umkreisen, wobei der Trend zu grossen, auf Plattformen montierten Relaisstationen mit riesigen Solargeneratoren geht. Kommunikationssatelliten sind aber nicht nur zur Ubertragung von Fern sprech- und Fernsehsignalen geeignet, sondern werden immer stärker für die Daten- und Textkommunikation, für die elektronische Briefübermitt lung und für Konferenzschaltungen verwendet werden. Zu den vielfälti gen Einsatzfällen gehören auch die mobilen Dienste, die Verbindungen zu Schiffen und Flugzeugen und auch zwischen Satelliten umfassen. Darüber hinaus gibt es Satelliten zur Navigation und Erderkundung, ja selbst zur Gewinnung und elektrischen Ubertragung von Sonnenenergie zur Erde sind Satelliten im Gespräch.

The first edition of Satellite Communications Systems Engineering (Wiley 2008) was written for those concerned with the design and performance of satellite communications systems employed in fixed point to point, broadcasting, mobile, radio navigation, data relay, computer communications, and related satellite based applications. This welcome Second Edition continues the basic premise and enhances the publication with the latest updated information and new technologies developed since the publication of the first edition. The book is based on graduate level satellite communications course material and has served as the primary text for electrical engineering Masters and Doctoral level courses in satellite communications and related areas. Introductory to advanced engineering level students in electrical, communications and wireless network courses, and electrical engineers, communications engineers, systems engineers, and wireless network engineers looking for a refresher will find this essential text invaluable.
