In the drilling field, inertial devices is greater and more adaptable than flying field, because of its poor working conditions, environmental temperatures are high, the temperature of adaptation and life requirements are very demanding, HT-T4 dynamically tuned gyro is designed for the case of the drilling field, overcome the above technical difficulties, its operating temperature up to 100 ℃.
