About this eBook

Small satellite technology is opening up a new era in space exploration offering reduced cost of launch and maintenance, operational flexibility with on-orbit reconfiguration, redundancy etc. The true power of such missions can be harnessed only from close and precise formation flying of satellites. Formation flying missions support diverse application areas such as reconnaissance, remote sensing, solar observatory, deep space observatories, etc. A key component involved in formation flying is the guidance algorithm that should account for system nonlinearities and unknown disturbances. The main focus of this book is to present various nonlinear optimal control and adaptive guidance ideas to ensure precise close formation flying in presence of such difficulties. In addition to in-depth discussion of the relevant topics, MATLAB program files for the results included are also provided for the benefit of the readers. Since this book has concise information about the various guidance techniques, it will be useful reference for researchers and practising engineers in the space field.

About the author

Dr. Mathavaraj S is a space scientist working at the Indian Space Research Organization (ISRO). He earned his Bachelor of Engineering in Aeronautical Engineering from Hindustan College of Engineering, Padur, followed by Master of Technology in Aerospace Engineering from Indian Institute of Technology, Madras and Ph.D. in Aerospace Engineering from Indian Institute of Science, Bengaluru. His interest in space dynamics made him pursue his career in Flight Dynamics Group at U. R. Rao Satellite Center (URSC) of ISRO. His contributions at ISRO include maneuver strategy design for geostationary orbit and lunar capture orbits, attitude profile generation during engine firing and constrained trajectory optimization for soft lunar landing. He is also passionate about formation flying of satellites. For his contribution in the space field, he received ISRO's Young Scientist award in 2018.
