Inertial Navigation
Inertial Navigation is a navigation technique 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. In aviation, Inertial Navigation Systems (INS) are used as a primary means of navigation on long-range aircraft and in situations where other forms of navigation are not available or reliable. INS provides accurate and continuous navigation information, which is essential for flight planning, guidance, and control.
