Introduction

ER-NSM-1 North Seeking Module

Introduction

ER-NSM-1 is a north-seeking type module based in MEMS gyro and accelerometer, specially designed for north-seeking, orientation and initial alignment use in surveying tools/gyro tools, mining/drilling equipment, unmanned aircraft launch systems, satellite antennas, target tracking systems, etc..

ER-NSM-1 is specifically designed for north-seeking applications. Its advanced differential sensor design can resist the influence of linear acceleration, enabling it to operate in extremely harsh environments, even in the presence of shocks and vibrations.
