An analysis of the physical principles of inertial navigation and its associated sources of errors including compensations to address these influences. Titterson (principal scientist, DRA) and Weston (navigation consultant, Sperry-Sun Ltd.) introduce the fundamental principles and historical development of inertial navigation and strapdown technology, detailing gyroscope, accelerometer and multi-sensor technologies, testing and calibration, strapdown systems and navigation computation, system alignment, and integrated navigation systems.
