"The Present and Future of Indoor Navigation" provides a complete overview of the latest indoor navigation technologies, algorithms, and systems. It begins by discussing various types of sensors that can be used for indoor navigation, such as accelerometers, gyroscopes, barometers, magnetometers, and cameras. It covers the various algorithms that can be used to compute the navigation solution, including Kalman filtering, particle filtering, and machine learning. Also discusses the system implementation considerations for indoor navigation, such as infrastructure, data fusion, and security. The book's focus is on present technologies and algorithms, but it also provides a look into the future possibilities for indoor navigation, making it a great resource for a wide audience. This includes researchers, engineers, and students who are interested in indoor navigation. It is also a valuable resource for anyone who wants to learn more about the latest technologies and algorithms for indoor navigation.
