Attention:
The same inertial reference systems are installed permanently on Polar 5 and Polar 6.
Summary
An inertial ravigation system is a navigation device that uses a computer, motion sensors (accelerometers) and rotation sensors (gyroscopes) to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references.
