GS16488 10-DOF High-Performance IMU
GS16488 combines 3-axis gyro, accelerometer, magnetometer, and barometer into a true 10-DOF inertial solution. With gyro bias 0.5°/h and accelerometer bias 10μg, it delivers precision previously found only in larger systems. The 44×47×14mm package supports SPI interface and operates from -40°C to +85°C. Designed as a drop-in replacement for imported IMUs, it serves gimbal stabilization, rail inspection, and UAV navigation with uncompromised performance.

Product Introduction
Inertial measurement Unit GS16488 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 GS16488 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.
