Ring Laser Gyroscope is a single axis laser gyro angle sensor designed and developed for high accuracy launch vehicle navigation systems. They are well suited for high precision strap down Inertial Navigation Systems (INS) due to very high accuracy, high bias, scale factor stability, low scale factor non-linearity and wide dynamic range. A ring laser gyroscope consists of a ring laser having two counter propagating modes over the same path in order to detect rotation. It operates on the…
