The Principle Behind Gyros in ICBMS
The ring laser gyro uses laser light to measure angular rotation.
High accuracy, with better than 0.01°/hour bias uncertainty, and mean time between failures in excess of 60,000
Advantages
ability to withstand g forces, responsiveness to changes in orientation and position
hours.

Principle of operation
Sagnac Effect :
Rotation induces a small difference between the time it takes light to traverse the ring in the two directions
