CW-MSS1140
MEMS Integrated Inertial Navigation System
Product Overview
CW-MSS1140 is a lightweight and cost-effective vehicle positioning and orientation system. It can complete alignment autonomously and output accurate azimuth and horizontal attitude. Combined with external equipment such as odometers, it realizes autonomous positioning and navigation of the carrier.
It integrates Beidou satellite positioning and navigation information internally. By integrating inertial navigation and satellite navigation, it accomplishes carrier positioning and navigation.
Core Advantages
Supports north-seeking up to 3mil. Full-temperature calibration compensation from -45℃ to +80℃. Odometer input interface is available for dead reckoning navigation.
