Product Introduction
Inertial Measurement Unit OE-MI-488B is a localized high-performance, small-size, high overload-resistant inertial measurement device with gyroBias stability of 2°/h (Allan) and accelerometerBias stability of 50µg (Allan). They can be used for precise navigation, control and dynamic measurement. This series of products adopts high-precision MEMS inertial devices with high reliability and robustness, and can still precisely measure the angular velocity and acceleration information of moving carriers in harsh environments.
The inertial measurement unit, built-in GPS/BD single-frequency dual-mode satellite receiver, carries a three-axis magnetic sensor, and also integrates a barometric pressure sensor for altitude measurement. The working mode can be flexibly switched in the state of combined navigation, AHRS, vertical gyro and so on. It can meet a variety of combination navigation application requirements, especially suitable for UAV, vehicle navigation, surface navigation and other types of moving objects navigation and control.
This product is equipped with a new combination navigation fusion algorithm with independent intellectual property rights, which can realize high sensitivity tracking, accurate positioning in open space, and also meet the navigation applications in urban, deep forest, canyon and other terrain. The system has been carefully designed to reduce the size of the system with excellent combined navigation performance to an unprecedented compactness and minimize the mass.
Composition and function
Inertial Measurement Unit OE-MI-488B with built-in 3-axis gyro and 3-axis plus meter is used to measure the carrier's 3-axis angular rate and 3-axis acceleration. Through the serial port in accordance with the agreed communication protocol output after error compensation (including temperature compensation, mounting misalignment angle compensation, non-linear compensation, etc.) of the gyro, plus meter data.
Combined navigation system PA-GS488B in the inertial measurement unit based on three-axis magnetic sensors, barometric sensors, satellite receivers, and built-in combined navigation fusion algorithm. Output fused attitude, heading, speed, altitude, position, clock and other information.
