AI Technical Summary

Technical Problem

Existing navigation systems face challenges in accurately determining the position of an aircraft using radio beacons, particularly in areas around airports, due to the irregular distribution of beacons and the need for extensive data storage, which is computationally intensive and not compatible with real-time processing by onboard systems, especially when satellite signals are weak or malfunctioning.

Method used

A method utilizing an artificial intelligence algorithm to select an N-tuple of beacon identifiers, trained on a geographical area, to calculate the aircraft's position, ensuring compliance with RNP navigation performance criteria, including accuracy and integrity, by optimizing the selection of beacons through an ordered set of admissible N-tuples.

Benefits of technology

Enables accurate and real-time position calculation of an aircraft using radio beacons, meeting RNP navigation performance criteria, even in irregularly shaped areas around airports, with reduced computational requirements and efficient data storage.

Abstract

Method and electronic device for determining radio navigation beacons for an aircraft, computer program, navigation method and associated electronic navigation system. The present invention relates to a method for determining radio navigation beacons (210) for an aircraft. The method (210) is implemented by an electronic determination device and comprises the following steps: selection (230) of an N-tuple of beacon identifiers, N being greater than or equal to 2, from an estimated position of the aircraft; and supplying (240) the selected N-tuple to an electronic computing device, for calculating a new estimated position of the aircraft from the N beacons corresponding to the N identifiers of the selected N-tuple.During the selection step (230), the N-tuple is selected from a set of admissible N-tuples, obtained through the implementation of an artificial intelligence algorithm. The AI ​​algorithm receives the estimated position of the aircraft as input and provides the set of admissible N-tuples as output. See Figure 4 for the abbreviation.
