Description OF the Inertial Measurement Unit
Unità di misura inerziale LINS688B is an inertial measurement device with small volume and high overload resistance. Gyro bias in-run stability is 1.5°/ h (Allan), and accelerometer bias in-run stability is 20ug (Allan). It can be used for precise navigation, control and dynamic measurement of carrier. This series of products use high-precision MEMS inertial devices, which have high reliability and high firmness, and can still accurately measure the angular velocity and acceleration information of the moving carrier in harsh environments.
LINS688B has a built-in three-axis gyro and three-axis accelerometer for measuring the three-axis angular rate and three-axis acceleration of the carrier. The gyro and accelerometer data with error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.) are output through the serial port according to the agreed communication protocol, and the three-axis magnetic sensor and air pressure sensor are built in.
