Dynamically Tuned Gyro (DTG) is a non-liquid floating, dry elastic support, electromechanical flexible gyro. As a mature rigid body rotor gyroscope, its accuracy ranges from 0.01°/h to 1°/h. Power-tuned gyroscope, also referred to as dynamic gyro, has the advantages of simple structure, small size, light weight and low cost. It is widely used in military, civil, civil, civil, marine, missile, spacecraft, guidance and navigation systems, and oilfield exploration and development. In the field.


NS-DTG1 is with small size and strong shock resistance. It can be used for the system which with small space, was widely used in borehole gyro survey tools and well logging tools.  It is designed for dynamical orientation and positioning in the drilling field.
