Abstract

An augmented reality (AR) system for an aircraft obtains an aircraft pose, determines a passenger pose relative to a window, and computes a field-of-view of the passenger. Operations select a set of passenger-relevant points of information (POIs) from a database that satisfy a relevance rule to the real-world objects viewable by the passenger through the window. For each of the passenger-relevant POIs in the set, operations determine an AR indicia to be displayed, and an AR indicia pose where the AR indicia is to be rendered on a display device. Operations generate a display command based on the AR indicia and the AR indicia pose for the passenger-relevant POIs in the set. Operations provide the display command to the display device to display renderings of the AR indicias with the AR indicia poses to augment the real-world objects viewed by the passenger through the window.

Abstract

A position of an aircraft is computed, associated with the radius of a sphere centered around the estimated position of the aircraft and within which the actual position of the aircraft is located with a probability equal to or greater than a predefined threshold. For this purpose, the computation is based on distances from radio transmitters each having a fixed position in a geographical reference frame. The positions of the radio transmitters are converted into a terrestrial reference system, before solving a system of equations linking, in the terrestrial reference system, the position of the aircraft and the positions of the radio transmitters. After solving the system of equations, the position of the aircraft is converted from the terrestrial reference system into the geographical reference frame.

Abstract

A system including a module for acquiring source bases of terrain data corresponding to an area of a terrain, divided into a plurality of cells; each source base containing, for each cell, an elevation, a module for transposing each source base into a respective transposed base of terrain data corresponding to the area of terrain, divided according to a reference mesh into a plurality of transposed cells, each transposed base including, for each transposed cell, a transposed elevation, a module for evaluating a local consistency level, based on the comparison of the transposed elevation of the cell with the transposed elevation of the corresponding transposed cell of at least one other transposed base, and an assistance module configured to determine a navigation assistance datum for the aircraft, depending on the assessed local consistency level.
