INERTIAL MEASUREMENT UNIT

IMU stands for Inertial Measurement Unit. In tracking antenna systems, the IMU plays a central role in precise alignment and stabilization. It ensures that the antenna remains accurately pointed at the satellite even when the platform is in motion—such as on a vehicle or a ship.

Motion Sensing

The IMU measures linear accelerations and rotational movements along three spatial axes (x, y, z).

Orientation Determination

By integrating the measured angular velocities, the IMU can calculate the antenna’s current orientation in space.

Stabilization

On mobile platforms (e.g., vehicles, ships, or aircraft), the IMU helps keep the antenna stably aligned with a target despite platform motion.

Inertial Navigation

In combination with other sensors (e.g., GPS), the IMU enables continuous position determination, even when external signals are temporarily unavailable.
