Abstract

The invention relates to a performance navigation method based on a unified airborne bus, which is used to solve the technical problem of poor real-time performance in time synchronization and navigation error fusion estimation of the existing performance navigation method. Its technical solution is to transform the navigation information obtained by different interfaces and buses into a unified bus and transmit it to the performance navigation processing center; the performance navigation processing center automatically classifies redundant navigation signals to the Vertical and horizontal performance navigation analysis module; according to the navigation information provided, the vertical and horizontal performance navigation module performs vertical and horizontal navigation error calculation respectively according to the model proposed by the present invention and the fusion estimation method of equivalent measurement; according to the navigation error, according to the performance navigation requirements , real-time navigation is realized in terms of time synchronization and navigation error fusion estimation.

Description

Performance navigation method based on unified airborne bus Technical field [0001] The present invention relates to a performance navigation method, in particular to a performance navigation method based on a unified airborne bus. Background technique [0002] Performance navigation (PBN) has many advantages over sensor-based navigation, for example: it reduces the need to maintain specific The need for sensor routing and cost, avoiding the manipulation of specific sensors requiring navigation system improvements, clarifies practical Time-based navigation (RNAV) application methods, etc.; airborne performance monitoring is to determine whether the navigation system is in accordance with the navigation performance (RNP) standard An important factor for quasi-execution, it involves both longitudinal and lateral navigation performance, which is closely related to the airborne bus; the airborne unified machine The proposed bus provides a basis for realizing information fusio...
