Abstract: The tape-suspended fully mechanical meridian gyroscope makes it possible to achieve the objective of north-seeking significantly more economically than before. The gyroscope is started up to the necessary rotational speed at the gyroscope cap thereof by an external force source in order to then rotationally move towards north, while suspended on the supporting tape, as a coast-down gyroscope. In order to stop a persisting rotation that goes beyond north, a damping means intervenes until a standstill is reached at north. In order to reliably achieve this, a system that can be finely adjusted with respect to the friction forces is used as the damping means. The north-seeking system according to the invention should be used especially in tunnel construction and in road construction, in azimuth finding, in mountainous terrain, and in many special technical tasks. Failures having electrical or electronic causes do not occur.
