1. IntroductionThe inertial navigation system (INS) is an autonomous navigation system that operates independently of external information, offering the advantages of discreet operation and robust anti-interference capabilities. However, a notable drawback of INS is the rapid accumulation of errors over time, making it challenging to rely on for prolonged and highly precise navigation [1,2,3,4,5].
