Product Description

High Precision Navigation MEMS IMU for Inertial navigation with built-in 3 Axis Gyro
 

Product Description

The KT-EX 9-2 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:
   1. ± 450º/s dynamic measuring range;
   2. Zero-bias stability: 5.1 °/h
2. Triaxial digital accelerometer:
   1. ± 18 G dynamic measuring range;
   2. Zero-bias stability: 0.07mg (ALLAN);
3. High reliability: MTBF > 20000h;
4. Guaranteed accuracy within the full temperature range (-40 ºC ~ 70 ºC): built-in high-performance temperature calibration and compensation algorithm;
5. Suitable for working under strong vibration conditions;
6. Interface 1 channel UART, 1 channel SPI, 1 channel CAN
