Patent ID: 7447590

Claim:
Aircraft piloting aid system, with GNSS-IRS hybridation, designed for onboard installation in an aircraft, comprising: an inertial reference system IRS with at least two inertial reference units, each supplying a set of inertial data and at least; a first multimode receiver supplying a first set of guidance signals and a first set of augmented GNSS data, a second multimode receiver supplying a second set of guidance signals and a second set of augmented GNSS data, each receiver including two digital processing boards with a mutual checking function for the data generated by each of said digital processing boards to supply said set of guidance signals, and a single augmented GNSS signal processing board, supplying said respective set of augmented GNSS data, wherein a function for generating guidance data from the GNSS data and the inertial data with integrated fault detection is performed in a distributed manner by said inertial reference units and said digital processing boards of said multimode receivers.
