Inertiajärjestelmät
Inertiajärjestelmät, often translated as "Inertial Systems" or "Inertial Navigation Systems" (INS), are self-contained navigation and guidance systems that continuously determine a vehicle's position, orientation, and velocity without the need for external references. They achieve this by employing inertial sensors, primarily accelerometers and gyroscopes. Accelerometers measure linear acceleration, while gyroscopes measure angular velocity.
These sensors are typically arranged in a gimbals system or, more commonly in modern applications, a strapdown
The core advantage of inertiajärjestelmät is their independence from external signals, such as GPS or radio
