The invention belongs to marine instrumentation and can be used to improve the accuracy of determining the course of the vessel or other moving object during swinging, in particular in storm conditions.
The declared gyrocompass contains a horizon indicator and a control channel to bring the gyrocompass to the meridian at the signal ofthe indicator and the horizon passed through the filter unit located behind the horizon indicator. At the same time, the specified filter unit is implemented as a third-order polynomial frequencyfilter:
where B1, B2, B3, Filter coefficients;
P – differentiation operator.
The invention consists of increasing the accuracy of the gyrocompass during swinging and the possibility of installing a gyrocompass at a distance of at least 20 m vertically from the center of mass of the vessel while maintaining the permissible value of the error.
