Embodiment Construction

[0021] In the process of realizing the present application, the inventors found that the navigation system, as one of the core components of the solid launch vehicle, directly affects the navigation accuracy, reliability and orbit entry index of the rocket system. At present, solid launch vehicles pursue the development idea of ​​low cost and high performance, so the navigation system often adopts Global Navigation Satellite System (GNSS) and strap-down inertial navigation system (Strap-down Inertial Navigation System, SINS) through the Kalman filter algorithm However, in actual engineering applications, GNSS characteristics are easily disturbed by the external environment, and its noise characteristics will change accordingly, which will easily cause Kalman filter divergence and affect the reliability and accuracy of the navigation system.

[0022] In view of the above problems, an embodiment of the present application provides a fault-tolerant processing method, including: ac...

Abstract

The embodiment of the invention provides a fault-tolerant processing method and device, a storage medium and an electronic device. The method comprises the following steps: obtaining the measurement information of an integrated navigation system in a solid carrier rocket, wherein the measurement information comprises SINS information and GNSS information; performing first fault-tolerant processingon the SINS information to obtain a first fault-tolerant processing result; performing second fault-tolerant processing on the GNSS information to obtain a second fault-tolerant processing result; and obtaining integrated navigation information of the solid carrier rocket through a Kalman filtering algorithm according to the first fault-tolerant processing result and the second fault-tolerant processing result. By adopting the scheme in the invention, the filtering accuracy is enhanced, so that the robustness and reliability of the GNSS / SINS integrated navigation algorithm are improved.

Description

technical field [0001] The present application relates to navigation guidance and control technology, in particular, to a fault-tolerant processing method and device, a storage medium, and an electronic device. Background technique [0002] As one of the core components of solid launch vehicles, the navigation system directly affects the navigation accuracy, reliability and orbital indicators of the rocket system. [0003] In actual engineering applications, because GNSS characteristics are easily disturbed by the external environment, its noise characteristics will change accordingly, which will easily cause Kalman filter divergence and affect the reliability and accuracy of the navigation system. [0004] In the related art, there is no effective solution for the problem that the GNSS characteristics in the navigation system are affected by the interference of the external environment and the navigation system is affected. Contents of the invention [0005] The embodime...
