Rotation rate measurement arrangement for rotating flying object

摘要

A rotational speed measurement device for rotating missiles, preferably comprising three mutually perpendicular micro mechanical rotational speed sensors (30) which are embodied as capacitively excitable, resettable read-out systems arranged together on a single platform (9) which can be rotated by a servo-circuit to enable rotational decoupling of said rotational speed sensors. The inventive rotational speed measurement device is characterised by high bias and scale factor stability which can be monitored at any given moment, resulting in accurate angle references at any given moment.
