Abstract

The invention discloses a neural network integrated navigation method. The method comprises the following steps of enabling signals to correspond, decomposing the signals of a navigation system, processing decomposition coefficients, forecasting and estimating a neural network of errors, building information of the errors of the navigation system, and correcting integrated navigation information. According to the neural network integrated navigation method, observed quantity which objectively exists is completely processed, a model is not related to, calculated quantity is small, and limiting of noise does not exist. Basically, an objective state is corrected by means of objective observation, correcting ability is strong, and an abstract state is not affected and controlled.

Description

technical field [0001] The invention belongs to the field of navigation, and in particular relates to a neural network combined navigation method. Background technique [0002] With the gradual completion of the Beidou satellite navigation system, the application of the Beidou system as a navigation platform is becoming more and more extensive, especially the organic combination with other navigation systems, not only can make full use of the information of various sensors to obtain high-precision position, Attitude and various dynamic navigation parameters, and the integrated navigation system also has high reliability, can adapt to various complex environments, and meets the requirements of modern weapon systems for precision, flexibility and high reliability. [0003] However, due to the lack of in-depth research on the Beidou system, the established model is not perfect. If the model is based on this model, it will have a negative impact on the application and developmen...
