ERICCO INERTIAL TECHNOLOGY ER-MIMU-101 North-seeking MEMS IMU Introduction ER-MIMU-101 is a micromechanical technology (MEMS)-based inertial measurement unit (IMU). which has the advantages of small size and light weight. Built-in three-axis gyroscope and three-axis accelerometer for measuring the three-axis angle parameters of the carrier, such as angular velocity, acceleration. The output data after error compensation (including temperature compensation, installation dislocation angle compensation, nonlinear compensation, etc.) are solved to obtain carrier attitude, velocity, displacement and other information. ER-MIMU-101 uses a high-precision and high-reliability MEMS accelerometer and gyroscope. It can be used for precise navigation, control, and dynamic measurements. Even in harsh environments, angular velocity and acceleration information of moving carriers can be accurately measured. Features Three-axis digital gyroscope: The bias instability can be up to 0.01 º/h (Allan variance); Bias Repeatability: 0.1 º/h Angle random walk: <0.0025º/√h. Three-axis digital accelerometer: Dynamic measurement range: ±30g; Bias instability: 10ug (Allan variance); Ensure accuracy over the full temperature range (-40°C~80°C): Built-in high-performance temperature calibration and compensation algorithm; Low power consumption: 2W Communication interface: RS422 Application High-precision attitude measurement, stability control, positioning Attitude control in UAV launch systems, satellite antennas, target tracking systems, etc Attitude measurement and control of precision platforms Navigation-level Navigation in a MEMS system Land Survey/Land Mobile Mapping System Railway train system monitoring and control, etc Whatsapp/Wechat/Mob:8613992884879 Websit : www.ericcointernational.com E-mail : ericco001@ericcointernationa

Product composition and working principle 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. Product technical characteristics a)The product is designed for miniaturization and low power consumption; b)Products with wide...

1) Installation error description Internal orthogonal compensation has been carried out for the whole product. If the platform used by the product cannot guarantee the accuracy of the benchmark after installation, please compensate the installation error accordingly. When the product is installed, it should be tightly installed parallel to the base level of the carrier installation (the installation error with the base level should be less than 0.05°). Because the product is a precision test instrument, although there is a shell protection, in order to protect the product damage, users should...
