Jianjun Zhang – författare

This book examines the autonomous management of spacecraft, which uses modern control technologies such as artificial intelligence to establish a remote intelligent body on the spacecraft so that the spacecraft can complete its flight tasks by itself. Its goal is to accurately perceive its own state and external environment without relying on external information injection and control, or rely on external control as little as possible, make various appropriate decisions based on this information and user tasks, and be able to autonomously control spacecraft to complete various tasks.

State of the art resource covering key technologies and related theories of inter-satellite links

Laser Inter-Satellite Links Technology explores satellite networking as a growing topic in the field of communication technology, introducing the definition, types, and working frequency bands of inter-satellite links, discussing the number of orbital elements of the spacecraft motion state under two-body motion and their conversion relationship, and establishing the basic demand model for inter-satellite link network, chain topology model, and transmission protocol model.

The book focuses on the analysis and introduction of the principles and error sources of microwave and laser inter-satellite ranging, including the basic composition, workflow, and constraints of the laser inter-satellite link, and related design principles of the inter-satellite laser transmitter and receivers. Later chapters also discuss theories and methods of acquisition, alignment, and tracking, the impact of alignment errors on performance, and inter-satellite link modulation and its implementation.

Specific sample topics covered in Laser Inter-Satellite Links Technology include:

Laser Inter-Satellite Links Technology serves a completely comprehensive resource on the subject and is a must-have reference for experts and scholars in aerospace, along with graduates and senior undergraduates in related programs of study.

Since China began an era of market reform three decades ago, many Westerners believed that, political liberalization and, eventually, democracy would follow. However, contrary to Western expectations, China remains an authoritarian country and the communist party is still in power, even though the country has witnessed rapid economic growth and its people have become richer.

In Marketization and Democracy in China, Jianjun Zhang questions whether China’s market reforms have created favorable social conditions for democracy, whether the country’s emerging entrepreneurial class will serve as the democratic social base, and the role of government in the process of transition. Based upon a careful analysis of two regions—Sunan and Wenzhou —the two prototypical local development patterns in China, Zhang finds that different patterns of economic development have produced distinct local-level social and political configurations, only one of which is likely to foster the growth of democratic practices. The results suggest that China’s political future is largely dependent upon the emerging class structure and offer a warning on China’s development: if market reforms and economic development only enrich a few, then democratic transition will be unlikely.

Marketization and Democracy in China will be of interest to scholars of Chinese politics, political science and development studies.

Integrate cutting-edge technology into spacecraft design with this groundbreaking work

Artificial intelligence and machine learning have revolutionized virtually every area of computing and complex engineering, and the design of satellite spacecraft is no exception. Intelligent satellites are increasingly capable of human-like perception, decision-making, and operations, and their problem-solving capacities are still expanding. As AI and machine learning continue to advance, their integration into satellite manufacture will only deepen.

Intelligent Satellite Design and Implementation seeks to understand the foundations of this integration and its likely directions in the coming years. Beginning from the basic principles of interaction between artificial intelligence and satellite design and mission planning, the book analyzes a series of current or potential areas of technological advancement to create a comprehensive overview of the subject.

Intelligent Satellite Design and Implementation readers will also find:

Intelligent Satellite Design and Implementation is ideal for graduate students and advanced undergraduates in engineering, computing, and spacecraft design programs, as well as researchers in these and related fields.

This book helps to solve the problems and challenges of satellite sensing in the current environment of increasing communications bandwidths and multiplicity of electromagnetic signals. It presents technology that makes full use of the broadband low-loss advantages of optoelectronic technology and research into new broadband radio-frequency channelization and receiving technology based on photoelectric sensing.

The methods presented allow improvements in system performance in terms of receiving bandwidth, frequency-sensing accuracy, channel equalization, adjacent channel crosstalk, dynamic range, and complexity of the system structure. In addressing the difficulty of satellite spectrum control, including the issue of high-precision and real-time wide-spectrum sensing not being able to be obtained simultaneously, the book solves the problem of accurate and parallel-decomposition sensing technology using the dual-phase optical frequency comb. This method avoids the involvementof fine filtering and does not require fine alignment between the source and the filter but achieves high perceptual accuracy.

Satellite Photoelectric Sensing Technology explores the research background, significance, and current challenges associated with the technology, making it relevant and interesting to academics, practitioners, and postgraduate students in this field.
