Abstract
In the field of autonomous navigation, the accuracy of the inertial navigation system (INS) heavily relies on the initial position information. Typically, this information is obtained from the global navigation satellite system(GNSS) or celestial navigation system (CNS). In this study, we present a novel approach for acquiring precise initial position information using the INS/CNS integration system. This method enables the independent determination of the carrier’s high-precision initial position in a static state. The experiment results show that the latitude error is 48.35m and the longitude error is -55.80m of this approach, which provide compelling evidence for the effectiveness of the proposed celestial positioning method.
