CW-MSB1330
MEMS Integrated Inertial Navigation System
Product Overview
CW-MSB1330 integrates high-performance MEMS gyroscopes, MEMS accelerometers and GNSS satellite receiver chips. By sensing the angular rate and acceleration of carrier motion, it receives real-time data from GNSS dual antennas or heading angle, and performs navigation calculation to obtain real-time carrier heading angle, 3D velocity, position and attitude information.
Core Advantages
Full-band GNSS support, ultra-low 3W power consumption, built-in adaptive attitude algorithm. When GNSS signal is lost, self-correction algorithm maintains horizontal attitude accuracy. Supports RTK differential input, zero velocity update and vehicle constraint algorithm.
