Laser Inter-Satellite Links Technology

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

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 Inter-Satellite Links Technology include:

• Pulse position modulation (PPM), Differential Pulse Position Modulation (DPPM), Digital Pulse Interval Modulation (DPIM), and Double-head pulse interval modulation (DH-PIM)
• Basic demand model of inter-satellite link network application, including basic configuration of constellations and inter-satellite transmission networks
• Inter-satellite ranging accuracy, principles of microwave inter-satellite ranging, and analysis of microwave ranging error sources
• Effect of tracking error on the beam distribution at the receiving end and influence of tracking and pointing error on communication error rate

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.
