NF1400 north finder is mainly used to determine true north orientation and horizontal attitude, and has the function of short-term dynamic orientation and attitude maintenance. It is mainly composed of high-precision MEMS gyroscope and accelerometer, micro servo motor, solution processing unit, etc. The true north is determined by multiple positioning method. It has the characteristics of high precision, small size and low cost, and is suitable for mining, field survey and other applications. The main characteristics are as follows:
Small size, easy to carry;
The multi position north finding algorithm is adopted, and the north finding accuracy is up to 0.2 °, without binding coordinate values;
The north seeking time is better than 3 minutes;
The horizontal attitude accuracy is up to 0.06 °;
The working temperature is -40 ℃~60 ℃;
The size is only 58mm × 44mm × 58mm
