– Portable options available for size-constrained applications.

**Applications**: Ideal for coal, oil, and gas industries; enhances efficiency and cost reduction in mining operations.

In the field of oil and coal mining, it is very important to obtain accurate north information. In terms of the selected methods, north-finding technology mainly includes inertial method, astronomical observation method, geodetic method, satellite positioning method and other methods. However, in complex terrain conditions such as underground tunnels or underwater, except for the inertial method, other methods will be restricted to varying degrees, and either have low accuracy or cannot be implemented at all.
The inertial north-seeking technology of the north finder is not affected by natural conditions or the environment, can independently complete the north-seeking task, and has the characteristics of long continuous working time and high accuracy, so it is the most commonly used.
Micro-Magic Inc has a FOG north finder NF 2000, which uses a closed-loop fiber optic gyroscope as its core component and can provide the carrier with a true north azimuth. Let’s see what’s special about it!
