CW-MSS1010 Series MEMS Integrated Inertial Navigation System

CW-MSS1010 Series
MEMS Integrated Inertial Navigation System

Product Overview

The CW-MSS1010 series integrates high-performance MEMS gyroscopes, MEMS accelerometers and GNSS satellite receiver chips. By sensing the earth's rotation angular rate and acceleration, it performs static self-alignment to obtain the true heading of the carrier. It implements integrated navigation by fusing 3D velocity, position and heading data acquired from the GNSS receiver.

Core Advantages
