Title
(EN) SYSTEMS AND METHODS FOR DETERMINING QUALITY AND INTEGRITY OF SOURCE INFORMATION TO DETERMINE NAVIGATION INFORMATION OF AN OBJECT
(FR) SYSTÈMES ET PROCÉDÉS POUR DÉTERMINER LA QUALITÉ ET L'INTÉGRITÉ D'INFORMATIONS DE SOURCE AFIN DE DÉTERMINER DES INFORMATIONS DE NAVIGATION D'UN OBJET
Abstract
(EN) A navigation system for determining quality and integrity of source information includes one or more data sources that provide the source information, a situation module that provides situation data, an information module that determines an estimate of the quality and an estimate of the integrity of the source information based on the source information and the situation data, an integrity monitor module that determines the integrity and the quality of the source information based on the estimate of the quality and the estimate of the integrity of the source information from the information module, and that validates the source information based on the integrity of the source information and/or the quality of the source information, and a navigation state estimator that determines the navigation information of the one or more objects based on the validated source information and corresponding quality of the source information received from the integrity monitor module.
(FR) L'invention concerne un système de navigation pour déterminer la qualité et l'intégrité d'informations de source, comprenant une ou plusieurs sources de données qui fournissent les informations de source, un module de situation qui fournit des données de situation, un module d'informations qui détermine une estimation de la qualité et une estimation de l'intégrité des informations de source en se basant sur les informations de source et les données de situation, un module de surveillance d'intégrité qui détermine l'intégrité et la qualité des informations de source en se basant sur l'estimation de la qualité et de l'estimation de l'intégrité des informations de source provenant du module d'informations, et qui valide les informations de source en se basant sur l'intégrité des informations de source et/ou de la qualité des informations de source, et un estimateur d'état de navigation qui détermine les informations de navigation desdits objets en se basant sur les informations de source validées et de la qualité correspondante des informations de source reçues de la part du module de surveillance d'intégrité.
