A tactical grade inertial measurement device

[diana]

Today, microelectromechanical systems (MEMS) inertial sensors and inertial systems have become an indispensable development direction for future navigation technology. MEMS technology is widely used due to its advantages such as small size, light weight, low power consumption, low cost, and impact resistance. At present, the development of MEMS inertial technology is relatively mature. It forms a combined system with auxiliary systems such as gyroscopes and accelerometers to provide suitable solutions for most navigation applications. The inertial measurement unit developed by Ericco is divided into MEMS IMU and FOG IMU. MEMS inertial measurement units are divided into tactical grade and navigation grade. Navigation-grade IMUs can seek north independently, while tactical-grade inertial measurement units can rely on magnetometers or GNSS to find north. Below we will introduce and recommend an ERICCO tactical grade IMU.

Next, we mainly learn about a new inertial measurement unit - ERICCO INERTIAL SYSTEM tactical-grade inertial measurement unit: ER-MIMU03 (high-precision navigation/stability control MEMS IMU).

ERICCO launches tactical-grade inertial measurement unit (IMU): ER-MIMU03 uses high-quality and reliable MEMS accelerometer and gyroscope. Equipped with three-axis precision gyroscopes of (complement code) numerical temperature, angle, accelerometer hexadecimal temperature, acceleration hexadecimal complement); It can also output floating point dimensionless values of gyroscope and accelerometer data processed by underlying calculations. ). The IMU has a built-in acceleration sensor and gyroscope, which can measure linear acceleration and rotational angular velocity in three directions, and obtain the attitude, speed and displacement information of the carrier through analysis. Applications for this tactical-grade IMU include azimuth, attitude, position measurement and maintenance in GNSS-assisted INS. Heading, pitch, roll measurement in UAV AHRS Robot control and control of autonomous machines, UAV directional stabilization and control of satellite antenna pointing, target tracking system Guidance, navigation and control attitude and attitude IMU orientation in tactical MEMS weapon systems Corner retention and positioning. Motion survey and maintenance of MRU and other application areas.

The high-precision navigation/stability control MEMS IMU integrates a three-axis MEMS accelerometer and a three-axis MEMS gyroscope in a unique redundant design that maximizes performance while reducing device size.

In terms of performance specifications, the high-precision navigation/stability control MEMS IMU has excellent gyroscopes and accelerometers. The gyroscope has a bias instability of 0.3°/h. Achieve long-term dead reckoning and maintain excellent heading performance. The MEMS sensor in ER-MIMU03 has extremely low vibration correction errors and can withstand high vibration environments up to 6.06g.

With extremely low gyroscope bias instability, the navigation performance of the high-precision navigation/stability control MEMS IMU can work normally when GNSS is interfered with or has no signal. This tactical-grade IMU has relatively high accuracy compared to tactical-grade IMUs from other peer companies. If you want to purchase our IMU, please contact our relevant personnel.
