Introduction

ER-POS-1 High Precision Land Positioning and Orientation System

Introduction

ER-POS-1 Series High Precision Land Positioning and Orientation System is based on high precision fiber optic gyroscope and quartz accelerometer as the core components, also composed of an inertial measurement unit, data acquisition and processing unit, and control display unit. At the same time, according to the application characteristics, it can integrate GPS/GNSS/BD receivers, odometer sensors, altimeters, star sensors and so on. The product can provide the information of heading, attitude, speed and position information of the carrier and be widely used for dynamic/static initial alignment, positioning, navigation of missile launch vehicle, armored vehicle, tank, surface ship, merchant vessel etc.
