AI Technical Summary
Technical Problem
Existing aircraft navigation systems struggle to accurately determine whether an aircraft is stationary on the ground due to multipath interference in radio frequency signals and noise in inertial navigation systems, leading to inaccuracies in current position information.
Method used
An avionics system on board the aircraft uses multiple information sources, including both inertial and non-inertial systems, with weighted voting to determine the aircraft's ground stop status, ensuring reliability by minimizing common disturbances.
Benefits of technology
The system provides accurate and reliable determination of the aircraft's ground stop status, enhancing the precision of current position information for navigation systems and autopilot functions.

Abstract
Avionics system and method for detecting a ground stop of an aircraft. The avionics system (10) for detecting a ground stop of an aircraft (1) is configured to: - acquire first ground stop information from a first set (12) of information sources (12a, 12b … 12n) configured to determine the first information based on signals from an inertial navigation system; - acquire second ground stop information from a second set (14) of information sources (14a, 14b … 14p) configured to determine the second information independently of signals from an inertial navigation system; - associate a weighting coefficient (w1a, w1b … w1n, w2a, w2b … w2p) with each of the first and second pieces of information;- determine an aircraft status related to its ground stop, by means of a voter (16) receiving as input each of the first and second information weighted by the weighting coefficient associated with it; and - transmit the aircraft status related to its ground stop, to a user system (18).
