I. Main technical features
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. The ground control box angle, azimuth, tool face angle and signal transmitted to the computer after mixing depth.
7. Computer ground data processing, display, save and draw a plane projection, can print three-dimensional trajectory map.
