DAIMU 501/701: Tactical-Grade All-in-One Centimeter-Level Navigation System

DAIMU 501/701: Tactical-Grade All-in-One Centimeter-Level Navigation System

DAIMU501 and DAIMU701 are tactical-grade, high-performance Inertial Measurement Units (IMUs) belonging to the DA5/7 premium series. This series integrates a high-precision array IMU, barometer, magnetometer, RTK (Real-Time Kinematic), and a multi-mode positioning system (supporting GPS/GNSS/BeiDou). Equipped with a high-performance MCU, the device features a compact and rugged design. As a highly integrated navigation solution, it directly outputs four key datasets—centimeter-level positioning, tactical-grade attitude, absolute heading, and altitude—without the need for external sensors or computing units. It is specifically designed for high-dynamic and harsh environments such as aerospace, UAVs, automotive, marine, and industrial machinery.

2. Product Features
