The GENIUS of Inertial Navigation Systems Explained

Moving-platform inertial navigation systems are miracles of engineering and a fantastic example of human ingenuity. This video explains and shows how they use accelerometers, gimbals and gyroscopes to determine the location of a vehicle, including the associated challenges they face such as transport wander and apparent drift. Huge thanks to Olaf for letting me use his footage!
