Technical Field

[0002] The laser strapdown inertial navigation system is a high-precision inertial navigation technology, and its core sensor is the ring laser gyroscope. RLG uses the Sagnac effect, which describes the phase difference between light propagating in the direction of rotation and light propagating against the direction of rotation when light propagates in a rotating ring cavity. This phase difference can be accurately measured and used to determine the rotation speed.

[0003] At present, laser strapdown inertial navigation systems are usually designed with specific types of ring laser gyroscopes in mind. This results in the system being difficult to interchange due to size differences, interface mismatches, or inconsistent electrical characteristics if the gyroscope needs to be replaced or upgraded;
