key word: LINS688B High Precision Inertial Measurement Unit
Details
LINS688B is a small volume, overload resistance of strong inertial measurement unit. It can be used for the precise navigation, control, and dynamic measurement of the carrier. The product uses the 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 the harsh environment.
LINS688B built-in three-axis gyroscope and three-axis accelerometer are used to measure the triaxial angular rate and triaxial acceleration of the carrier. The gyroscope and accelerometer data after error compensation (including temperature compensation, non-position compensation, misalignment angle compensation, nonlinear compensation, etc.) are output through the serial port according to the agreed communication protocol.
