Laser gyroscopes represent a pivotal technology in measuring Earth’s rotation with unmatched precision, utilising the Sagnac effect to detect minuscule angular variations. These instruments, often ...
Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...
