AI Technical Summary

Technical Problem

When the existing aircraft navigation system switches navigation mode and sensor failover, the navigation results are prone to problems such as drift, error, sudden changes, oscillation jumps, etc., resulting in low navigation quality.

Method used

By determining the available navigation sources, smoothing them according to changes in the navigation scheme, and using methods such as moving average, exponential moving average or weighted moving average to improve the stability and accuracy of navigation results.

Benefits of technology

It effectively improves the fluctuations and errors of navigation results caused by navigation scheme switching, improves navigation quality, and makes the navigation results closer to the true value of the aircraft state.

Abstract

The embodiment of the invention discloses a flight navigation processing method based on navigation change, and the method comprises the following steps: determining an available navigation source, and determining a navigation scheme according to the available navigation source; performing navigation calculation according to the navigation scheme, and determining an original navigation result at a certain moment or some moments according to a navigation calculation result; and determining a corresponding smoothing operation according to the change condition of the navigation scheme, and executing the smoothing operation on the original navigation result to determine a target navigation result.
