An inertial navigation system (INS) is a navigation aid that uses a computer, motion sensors (accelerometers) and rotation sensors (gyroscopes) to continuously calculate via dead reckoning the position, orientation, and velocity (direction and speed of movement) of a moving object without the need for external references. It is used on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Other terms used to refer to inertial navigation systems or closely related devices include inertial guidance system, inertial reference platform, inertial instrument, inertial measurement unit (IMU) and many other variations.

Famous quotes containing the word system:
“The individual protests against the world, but he doesn’t get beyond protest, he is just a single protester. When he wants to be more than that, he has to counter power with power, he has to oppose the system with another system.”
—Friedrich Dürrenmatt (1921–1990)
