The aim of this book is to introduce the novel approaches for the study of relative dynamics modelling， control， and design of formation and swarm flying. Broad research focuses of current interest are covered， with each chapter involved in different topics. The contents of this book include the introduction， definition， and property of orbital mechanics and control system in the framework of formation and swarm flying concepts using various theoretical methods and numerical simulations， which have potential merits in mission analysis and design.
　　The book is intended for researchers， teachers， and students of the universities and institutes in astrodynamics， control， and interdisciplinary space technology fields for the purpose of academic study and engineering application.
