Method to reduce operation errors of needle vibration gyro caused by imperfection of detector cross-section shape

The method of balancing the needle vibration gyro sensitive element of triangular cross-section is considered. Balancing allows to reduce requirements to accuracy of the sensitive element manufacturing to reach the same accuracy on zero signal and difference of resonance frequencies on the axes of the signal excitement and pickup. It is shown that the obtained model can be used also for other purposes, for instance, to select a rational scheme for excitement/pickup of the detecting element oscillation.
