1. Military standard; 2. Fully automatic; 3. Total station+gyroscope; 4. Integrated.

  Gyroscope, or gyro, is one of the most commonly used surveying equipments in the world. It is often seen in underground construction projects such as coal mining, tunnel drilling, and subway construction.

  As a brand product of Beijing Institute of Space Launch Technology, a branch of China Aerospace Science and Technology Corporation (CASC), BTJ series of gyroscopes  were formerly used for initial directing and orientation for missile launching.

  BTJ-5 total station gyroscope is a combination of a BTJ gyroscope and a total station, the latter is usually a Leica TS06 2", one with sound reputation worldwide.

  With a neutral, rapidly rotating gyroscope suspended inside the instrument, high accuracy is achieved with the BTJ-5 irrespective of the Earth's magnetic field. The gyroscope axis oscillates around geographic north as a result of the interaction of the gyro rotation,gravitational pull and the Earth's rotation. This enables a special electro-optical scanning system determine fully automatically where true north is with the utmost accuracy. It works fast-it takes just about 12 minutes to achieve a one-directional measurement with an accuracy of 5".

  Unlike traditional gyroscopes, BTJ-5 is fully automatic. With the press of a few keys, the rest will be done all by itself. It does not need the help of a compass to find the near-north direction, which is normally required for traditional apparatuses.It can work irrespective of weather condition, and it doesn't need to provide the known points.
