This dynamically tuned gyro is designed for the case of the drilling field, have overcomed the following technical difficulties, its operating temperature up to 100 degree centigrade. In the drilling field, inertial devices is greater and more adaptable than flying field, because of its poor working conditions, especially the higher environmental temperatures, therefore, the temperature of adaptation and life requirements are very serious.
