Jioptik STA-H688 High-precision Inertial Measurement Unit IMU is a inertial measuring unit with small size and strong overload resistance. It can be used for the precise navigation, control, and dynamic measurement of the carrier. The product uses high-precision MEMS inertial device, has high reliability and high hardness, and has the ability to accurately measure the angular speed and acceleration information of the mobile carrier in harsh environment.
Jioptik STA-H688 High-precision Inertial Measurement Unit IMU has a three-axis gyroscope and a triaxial accelerometer to measure the triaxial angular rate and triaxial acceleration of the carrier. After error compensation (including temperature compensation, installation dislocation angle compensation,Nonlinear compensation, etc.) of the gyroscope and accelerometer data are output through the serial port according to the agreed communication protocol.
High-precision MEMS is equipped with a 3-axis accelerometer, and a 3-axis gyroscope Optional ten-axis hardware: Add a 3-axis Magnetometer and digital barometer
