ABSTRACT:
The damping of the fiber coil of a fiber gyroscope is automatically corrected or newly determined in a microprocessor by repeating a calculation program in which a previously known damping factor of the fiber coil is replaced by a more recently determined damping factor. The calculation program is repeated until the calculated damping factor converges toward a fixed value. In this way, changes in the damping factor, e.g. due to aging of the fiber coil, due to splicings in the fiber coil, are ascertained and automatically corrected.
