本書以北鬥導航衛星系統(BDS)的設計理論和開發經驗為基礎,從工程的角度重點介紹了空間段和相關衛星技術以及星地一體化設計。
Based on the design theory and development experience of Beidou navigation satellite system (BDS), this book highlights the space segment and the related satellite technologies as well as satellite-ground integration design from the perspective of engineering.
本書中的衛星導航技術分為上行與接收技術、廣播鏈路技術、星間鏈路技術、時頻系統技術、導航信號生成與評估技術、導航信息管理技術、導航衛星自主運行技術。
The satellite navigation technology in this book is divided into uplink and reception technology, broadcasting link technology, inter-satellite link technology, time-frequency system technology, navigation signal generation and assessment technology, navigation information management technology, autonomous operation technology of navigation satellite.
最後,本書向讀者介紹了BDS等全球導航衛星系統的技術發展現狀和趨勢,並提出了未來發展的技術方向。
In closing, the book introduces readers to the technological development status and trend of BDS and other GNSS, and propose the technologies of future development.
與目前大多數關於這一主題的書籍主要集中在原理、接收機設計或應用方面不同,本書還提供了大量關於衛星系統在全球導航衛星系統中的作用和信號信息流過程,每一章不僅研究理論和主要技術,也專注於工程開發。
Unlike most current books on this topic, which largely concentrate on principles, receiver design or applications, the book also features substantial information on the role of satellite system in the GNSS and the process of signal information flow, and each chapter not only studies on the theoretical function and main technologies, but also focuses on engineering development.
因此,讀者不僅可以從整體上更好地了解衛星導航系統,還可以了解衛星導航系統的主要組成部分和關鍵技術。
Accordingly, readers will gain not only a better understanding of navigation satellite systems as a whole, but also of their main components and key technologies.
