inertiaalmõõtureid
Inertiaalmõõturid, also known as inertial measurement units (IMUs), are devices that measure and report a body's specific force, angular rate, and sometimes the magnetic field, using a combination of accelerometers and gyroscopes. These sensors are crucial for estimating orientation, velocity, and position in various applications. Accelerometers detect linear acceleration, which can be integrated over time to infer velocity and then position, though drift is a significant challenge with this method. Gyroscopes measure angular velocity, allowing for the tracking of changes in orientation.
The core components of an IMU are typically micro-electromechanical systems (MEMS) based accelerometers and gyroscopes. The
Inertialmõõturid find widespread use in navigation systems for aircraft, spacecraft, and submarines, where GPS signals may
