Low Dift Gyroscope Accelerometer Inertial Measurement Unit IMU

Low Dift Gyroscope Accelerometer Inertial Measurement Unit IMU


Product Description


The 16488HB multi-degree-of-freedom inertial measurement unit is a complete inertial system with a built-in three-axis gyroscope, a three-axis accelerometer, a three-axis magnetometer and a pressure sensor for measuring the three-axis angle of the carrier parameters such as rate, acceleration, three-axis magnetic field, air pressure, etc., output data after error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.) according to the communication protocol through SPI.

  1. Three-axis digital gyroscope:

    A) ± 2000º/s dynamic measurement range;

    B) Zero bias stability: 3 °/H (GJB, 10S, Z-axis), 0.8 °/H (ALLAN, Z-axis);

    2) Triaxial digital accelerometer:

    A) ± 200g dynamic measurement range;

    B) Zero bias stability: 0.4mg (GJB, 10S), 0.06mg (ALLAN);

    3) Triaxial digital magnetometer: 2.5g auss

    4) Digital barometer: 300mbar ~ 1100mbar

    5) High reliability: MTBF 20000h;

    6) Guaranteed accuracy within the full temperature range (-40 ℃ ~ + 80 ℃):

    built-in high-performance temperature calibration and compensation algorithm;

    7) Suitable for operation under strong vibration (6.06 G, 20 ~ 2000 Hz);

    8) Suitable for working under large impact conditions (1000 G, 0.5ms);
