Basic working principle and features:
1. FOG is an effect achieved by an optical SAGNAC advanced element angular rate measurements, mainly used in missile navigation and guidance, ship navigation and attitude control, positioning and orientation system. Compared with the conventional mechanical and electronic gyroscope, it has the characteristics of solid state structure, short start-up time, high dynamic range, high reliability, long life time.
2. The instrument uses a high-precision FOG azimuth measuring device, small size, long life, shock and vibration, small zero drift. It is the most ideal directional sensor for measuring the azimuth angle in the magnetic mine area and the iron casing, that is, the shortcoming of the power tuning gyroscope is avoided and the advantage of the power tuned gyroscope is improved.
3. The instrument uses a high-precision dual-axis tilt sensor as an angle measuring device, after 24 AD samples obtained after data processing vertex data.
4. The optimized tool surface angle measurement method, can accurately measure the orientation of the tool face angle and high-side tool face angle of the magnetic and non-magnetic mining area.
5. Application-optimized digital signal processing to optimize the measurement system to accurately measure the angle and azimuth, the measurement results to achieve high precision requirements; Dynamic Compensation technology to eliminate gyroscope zero drift, zero drift precision measurements.
6. Application of the technology of long wire transmission in digital communication, reliable transmission of long cable digital signal, and improve the anti-interference ability of the instrument.
7. Do not need to ground directional, you can always measure the true north azimuth drilling, saving time and effort, to ensure the accuracy of measurement.
8. The ground control box angle, azimuth, tool face angle and signal transmitted to the computer after mixing depth.
9. Computer ground data processing, display, save and draw a plane projection, can print three-dimensional trajectory map.
