Abstract

L'invention concerne un système de navigation comprenant un système inertiel (4, 4a) et un calculateur (6) déporté par rapport au système inertiel (4, 4a), dans lequel : • le système inertiel (4, 4a) est configuré pour : ○ générer des premières données inertielles, ○ horodater les premières données inertielles dans une première échelle de temps, à l'aide d'au moins un signal de datation dans la première échelle de temps, ○ transmettre les premières données inertielles horodatées au calculateur (6), • le calculateur (6) est configuré pour : ○ recevoir des premières données supplémentaires préalablement générées par un dispositif tiers (2), et également horodatées dans la première échelle de temps, ○ fusionner et/ou consolider les premières données inertielles horodatées avec les premières données supplémentaires horodatées, de sorte à générer des premières données de navigation.The invention relates to a navigation system comprising an inertial system (4, 4a) and a computer (6) offset from the inertial system (4, 4a), in which: • the inertial system (4, 4a) is configured for : ○ generate first inertial data, ○ time stamp the first inertial data in a first time scale, using at least one time stamping signal in the first time scale, ○ transmit the first time stamped inertial data to the computer ( 6), • the computer (6) is configured to: ○ receive first additional data previously generated by a third party device (2), and also time-stamped in the first time scale, ○ merge and / or consolidate the first time-stamped inertial data with the first additional time-stamped data, so as to generate the first navigation data.
