Introduction

Introduction
The product is mainly composed of three-axis MEMS accelerometer and gyroscope. The working principle is as follows: the gyroscope and accelerometer data are collected by ARM microcontroller, three high-precision gyroscopes are collected by 1-channel digital interface SPI, and three accelerometers are collected by another 1-channel digital interface SPI. All sensors are calibrated and compensated in software after acquisition.

Features
Gyro bias stability full temperature (10s 1σ):≤0.5°/h
Gyro bias repeatability total temperature (10s 1σ):≤0.1°/h
Accelerometer bias Stability (10s 1σ):≤0.05mg
Volume:120mm x Φ30mm

Application
Antenna and Line of Sight Stabilization Systems
Integrated Navigation Systems & Inertial Guidance System
Flight Control & Guidance System
Attitude Heading Reference Systems (AHRS)
Stabilization of Antennas, Cameras & Platforms
Aerial and Marine Geo-mapping / Surveying

Product use and function
The inertial measurement unit (hereinafter referred to as the product) consists of three high-precision MEMS gyroscopes and three accelerometers. The acceleration and angular rate of the three axes can be measured in real time, and the measurement results can be sent to the external application control system through the 1-channel asynchronous serial port RS422 as required.
