Systems 100, methods, and machine-executable programming products adapted for the control of aircraft or other vehicles by receiving from at least one Inertial Reference System (IRS) 102 comprising a plurality of Inertial Reference Units (IRUs) 110 signals representing vehicle state data; receiving from at least one Augmented Direct Mode Sensor (ADMS) 106 sig-nals representing independently-acquired vehicle state data corresponding to least a subset of the signals received from the IRS; performing signal selection and fault detection processes on the signals received from the at least one IRS and on the correspond-ing signals received from the ADMS; based at least partly on the signal and fault detection processes, determining whether at least one component of at least one of the IRS and ADMS is in a fault condition; and based on the determination whether the at least one component is in a fault condition, providing to at least one vehicle control system device one or more vehicle control com-mand signals.

Systèmes (100), procédés et produits de programmation exécutables sur machine, conçus pour commander un aéronef ou un autre engin, consistant à : recevoir dau moins un système inertiel de référence (IRS) (102) comprenant une pluralité de centrales inertielles de référence (IRU) (110) des signaux représentant des données relatives à létat de lengin; recevoir dau moins un capteur en mode direct rehaussé (ADMS) (106) des signaux représentant des données détat de lengin obtenues indépendamment et correspondant à au moins un sous-groupe des signaux reçus de lIRS; mettre en uvre des processus de sélection de signaux et de détection de défaillance sur les signaux reçus de lIRS et sur les signaux correspondants reçus de lADMS; en fonction en partie au moins des processus de sélection de signaux et de détection de défaillance, déterminer si au moins un composant de lIRS et/ou de lADMS est en état de défaillance; et, en fonction de cette détermination, transmettre à au moins un dispositif de commande dengin un ou plusieurs signaux de commande dengin.
