About the book

Used in the beginning as stand-alone systems for the rockets guidance, the inertial navigation systems (INSs) have become core components, along with GNSS, in integrated navigators developed for high precision aerospace applications. Between the most important applications developed, based on the INS support, can be mentioned the navigation of aircraft, tactical and strategic missiles, spacecraft, submarines and ships. This large spectrum of applications was generated firstly due to the main advantage of the INS to be a completely autonomous system (immune to jamming and deception), and secondly due to its simplicity in implementation. Moreover, the permanent improvement of manufacturing technologies for the inertial detection, but also the important changes related to the power of the data processing systems, extended the range of INS applications. Based on the new MEMS and NEMS inertial sensors technologies, the INS market provides small and light inertial navigation systems, offering the capabilities to be used, besides the usual applications with aircraft, satellites, UAV and MAV, in a lot of military and civilian applications, including the human and animal motion capture.

On the GNSS side, GPS, which is currently known as the most popular positioning system, covers an extremely large area of applications. Besides the aerospace applications, the last two decades shown an increasing trend in the use of positioning and navigation technologies in land-vehicle navigation, including here autonomous car navigation systems, farming, emergency assistance, package delivery, fleet asset tracking and management, construction, collision avoidance, mining, and environment monitoring. However, the GPS is still affected by a reduction in positioning accuracy when the satellite signal is blocked, diffracted, or reflected, its applicability in hostile environments still being a challenge. Having characteristics complementary to GPS, the INS has been widely adopted to assist GPS-based navigation systems. An INS/GPS integrated navigation system is able to provide improved navigation performance in terms of accuracy, availability, and reliability over the GPS-only system.

This book intends to provide the reader with a comprehensive overview at the level of all components implied in the development of the Navigation Systems based on INS, GNSS or both of them, including here the inertial sensors and signal conditioning algorithms on inertial measurement units - IMU (denoising, temperature effects estimation and compensation, filtering, etc.), the calibration and alignment techniques for INS, the redundant configurations of INS and system integrity monitoring algorithms, the INS modeling and analysis, the trends in GNSS technology and applications, INS/GNSS integration architectures and data fusion algorithms, and the fully developed systems for various military and civilian applications.

Teodor Lucian Grigorie

Military Technical Academy

Teodor Lucian Grigorie was born in 1975 in Craiova, Romania where he received the BsC and MsC in Aerospace Engineering from the Faculty of Electrical Engineering, University of Craiova, in 1998 and 1999, respectively. In 2006 he obtained the Ph.D. at the Faculty of Aerospace Engineering, Politehnica University of Bucharest in Aerospace Engineering field. From 1998 to 2005 he worked as an assistant professor at Avionics Division of University of Craiova, while from 2005 to 2009 he was a senior lecturer in inertial navigation systems at the same institution. Starting from 2009 until 2018 he was an associate professor at the Avionics Division of University of Craiova. Between May 2008 and February 2009 he was a postdoctoral fellow at the University of Quebec, Canada, institution with which collaboration was established for the purpose of research projects since 2002. Since October 2018 he is a First Degree Scientific Researcher at Military Technical Academy 'Ferdinand I” in Bucharest, Faculty of Aircraft and Military Vehicles, Center of Excellence in Self-Propelled Systems and Technologies for Defense and Security. Also, since October 2017 he is a Ph.D. supervisor at University Politehnica of Bucharest, Faculty of Aerospace Engineering. He authored or co-authored 4 books, 2 laboratory handbooks, 6 books chapters and more than 200 papers in journals and conference proceedings. His research activities concern aerospace navigation systems, miniaturized inertial sensors, avionics equipment and systems, automatic control systems, electric actuation systems (including smart material actuators) and morphing aircraft structures.
