Research on Temperature Processing Algorithm in Inertial Navigation System

The accuracy of the output data of inertial navigation system is closely related to temperature, so how to ensure the accuracy, stability and reliability of temperature acquisition is very important for inertial navigation system. Based on engineering practice and analysis and comparison of common temperature processing software methods, this paper proposes a smoothing algorithm for establishing temperature reference, which can eliminate possible extreme values and ensure that the temperature change rate is within the expected range, further reduce temperature fluctuations, and improve the accuracy of navigation operations and the stability of subsequent navigation operations.
