This book introduces typical inertial devices and inertial-based integrated navigation systems, gyro noise suppression, gyro temperature drift error modeling compensation, inertial-based integrated navigation systems under discontinuous observation conditions, and inertial-based brain integrated navigation systems. Integrated navigation is the result of the development of modern navigation theory and technology. The inertial navigation system has the advantages of strong autonomy, high short-term accuracy, all-day time, all weather, and so on. And it has been applied in most integrated navigation systems. Among them, the information processing of inertial-based integrated navigation system is the core technology. Due to the effect of the device mechanism and working environment, there are errors in the output information of the inertial-based integrated navigation system, including gyroscope noise, temperature drift, and discontinuous observations, which will seriously reduce the accuracy and robustness of the system. And the book helps readers to solve these problems. The intelligent information processing technology involved is equipped with simulation verification, which can be used as a reference for undergraduate, graduate, and Ph.D. students, and also scientific researchers or engineers engaged in navigation-related specialties.

This book offers a comprehensive exploration of indoor acoustic positioning systems designed for environments where GPS is ineffective. It thoroughly examines the design and implementation of sound-based positioning systems (SPS), focusing on methods such as Time of Arrival (ToA), Angle of Arrival (AoA), and Time Difference of Arrival (TDoA) to achieve accurate 3D localization. The book addresses challenges including Doppler shifts from moving robots, signal reflections (multipath) due to obstacles, and environmental factors like wind and temperature variations that affect acoustic signal propagation. By providing detailed analysis and practical mitigation strategies, it equips readers with solutions to enhance SPS accuracy and reliability. Special features include illustrative diagrams, comprehensive tables, and an appendix containing key function code for building a ToA-based acoustic positioning system—facilitating hands-on learning and implementation. This resource will be invaluable to robotics engineers, indoor navigation system developers, and researchers in autonomous systems who seek to design and deploy reliable indoor positioning solutions in GPS-denied environments.
