Abstract

Orienting toward the demand for long-endurance and high-precision autonomous navigation technology, it is of extremely significant practical importance to systematically tease out and review the development history and current status of key technologies of optical gyro rotating modulation inertial navigation systems (INS). Firstly, in light of the error characteristics of inertial navigation systems, the fundamental principle of rotating modulation technology is elaborated. This principle plays a crucial role in enhancing the accuracy and reliability of navigation. Secondly, a comprehensive review and analysis of the development history of rotating inertial navigation systems in Western countries such as Europe and the United States is conducted. The technical logic behind the evolution of these systems is examined, providing valuable insights for future development. Additionally, the current status of the development of rotating inertial navigation systems in China is summarized. Finally, with the aim of improving the autonomous navigation accuracy of the system, the key technologies and research status of rotating inertial navigation systems that need to be addressed are analyzed from three aspects: rotation strategy optimization, error calibration, and initial alignment. This in-depth analysis helps identify the challenges and opportunities in this field. Based on the summary of the optical gyro rotating modulation inertial navigation system and the development of key technologies, several thoughts are put forward for the subsequent research on rotating inertial navigation systems, which can serve as a valuable reference for the research on high-precision autonomous navigation technology.

Key words： laser gyroscope; fiber optic gyroscope; rotation modulation; rotation inertial navigation; rotation strategy; inertial navigation; error compensation; online calibration
