Introduction

The ER-MNS-09 is a MEMS gyroscopic directional module for well trajectory measurement device with a special-shaped cylindrical design. It uses high-precision MEMS gyroscope that can find the north by itself. It determines the geographic true north direction by measuring the earth's rotation component. It does not rely on the geomagnetic field and can work stably in underground mines, metal pipelines or strong electromagnetic environments.

It can realize azimuth measurement, real-time output of carrier attitude reference value and attitude holding function. It has strong anti-impact and vibration ability, small size, light weight and low power consumption, and is the most ideal equipment in the fields of mining, geophysical exploration, directional drilling, etc.
