M303B MEMS three-axis gyroscope

Introduction

M303B MEMS three-axis gyroscope adopts high-precision domestic gyroscope, combined with high-performance temperature compensation algorithm and inertial device calibration calculation method, which can output the angular velocity and internal temperature information of the carrier in the three axes of pitch, roll and heading in real time. This model of gyroscope uses 5V power supply. The communication interface type is RS422 serial interface. The gyroscope has the advantages of small size, low power consumption, light weight, high reliability, short start-up time and high precision, etc. and is suitable for seeker, photoelectric pod, turret image stabilization platform and so on so forth. The gyroscope can replace the STIM210 MEMS three-axis (dual) axis gyroscope in situ.
