CONT

In its simplest form, an inertial navigation system (INS) consists of an inertial measurement unit (IMU), the navigation computer, and a computer interface. Therefore, the inertial navigation system aboard an aircraft provides ... aircraft acceleration, velocity, position, attitude, and heading to the onboard navigation computer ... The IMU ... measures the specific force and attitude of the vehicle in an inertial coordinate frame. These inertial coordinates are in turn transferred to the computer, which determines the vehicle position in the desired reference frame.
