New Type North Finder Sensor For Well and Tunnel Measurement Using  

Introduction

North finder is mainly used to find true north automatically. It is composed
of MEMS gyro, dual axis accelerometer, mechanical rotation device and signal
algorithm electric circuit.
Mini gyro north finder use speed gyro to measure the component on reference
direction of earth rotation speed, then calculate heading angle. Because the earth
rotation speed is very slow and hart to detect, so polaris use a high accuracy servo
driving system to drive the one or more gyro gyro rotation, the north finder is not
affected by magnet field and it need to work on horizontal level and almost static
status.

Main feature

* reliable,IP65
* low power consumption,24V,0.5A
* not affected by magnetic interference, do not depend on satellite
* portable, size 14*17*13.5CM
* measure static roll and pitch, static accuracy: 0.2°
* static true north finding, 1σ north finding accuracy 0.5°secΦ(Φ local latitude)
* after finding north, measure carrier dynamic roll and pitch angle, heading angle
* dynamic accuracy0.1-0.3°/min(optional)

Application 

* weapon equipment
* equipment calibration
* construction
* well and tunnel measurement
