High Precision MEMS Inertial Measurement Unit KSIMU16495 with Wide Operating Temperature -40~75℃ and Solid Reliable Performance
Inertial measurement Unit KSIMU16495 is a domestic inertial measurement equipment with high performance, small size and high overload resistance. Gyroscope zero bias stability 0.5°/h (Allan), accelerometer zero bias stability 10µg (Allan). It can be used for precise navigation, control and dynamic measurement of weapons. This series of products adopts high-precision MEMS inertial devices, with high reliability and high robustness, and can accurately measure the angular velocity and acceleration information of the moving carrier in harsh environments.
The inertial measurement unit KSIMU16495 with built-in three-axis gyro and three-axis accelerometer is used to measure the carrier's three-axis angular rate and three-axis acceleration. Through the serial port according to the convention communication protocol output error compensation (including temperature compensation, installation misalignment Angle compensation, nonlinear compensation, etc.) gyroscope, accelerometer data, and built-in three-axis magnetic sensor, pressure sensor.
