Inertiaalipohjaiset

Inertiaalipohjaiset, often translated as inertial-based, refers to systems and technologies that rely on the principles of inertia. Inertia is the property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. These systems typically utilize sensors that measure acceleration and angular velocity to determine position, orientation, and movement without the need for external references like GPS or landmarks.

The core components of inertial-based systems are inertial measurement units (IMUs). An IMU typically consists of accelerometers and gyroscopes. Accelerometers measure linear acceleration along one or more axes, while gyroscopes measure angular velocity. By integrating these measurements over time, the system can estimate changes in velocity, position, and attitude.

Inertial navigation systems (INS) are a prominent application of inertial-based technology. INS can track a vehicle's position, velocity, and orientation by continuously monitoring its inertial parameters. These systems are vital in scenarios where external navigation aids are unavailable or unreliable, such as underwater, in space, or in GPS-denied environments.

Other applications include motion capture for animation and gaming, stabilization systems in cameras and drones, and the development of self-driving vehicles. While inertial-based systems can be very accurate over short periods, errors can accumulate over longer durations due to sensor drift and noise, necessitating periodic recalibration or fusion with other navigation sources.
