Abstract:
1. A device for determining location information, inertial primary references and anemo-barometric data consolidated for an aircraft, comprising: a circuit for determining location information comprising; a circuit for determining inertial primary references comprising: a circuit for determining anemo-barometric data comprising: air data measurement sensors for measuring anemo-barometric data indicating the movement of the aircraft relative to the air; air data consolidation means for consolidating the measured anemo-barometric data; air data reference computing means for computing anemo-barometric reference parameters of the aircraft from the consolidated anemo-barometric data; air data parameter consolidation means for consolidating the computed anemo-barometric reference parameters; wherein the radionavigation data consolidation means, inertial data consolidation means and the air data consolidation means each comprise a plurality of consolidation circuits, each of the consolidation circuits being associated with an index and comprising: a computation means for each of said circuit for determining location information, said circuitry for determining inertial primary references, and said circuit for determining anemo-barometric data, respectively, each computation means being linked to all of said measurement sensors of the corresponding one of said circuits, each of the computation means comparing the measurements of said measurement sensors of the corresponding one of said circuits to thereby detect malfunctioning measurement sensors; an ordered storage means for storing the results of the computation of each of the computation means of the others of the plurality of consolidation circuits ranking the results in ascending order of the indices associated with the consolidation circuits, from i+1 to n, and from 1 to i−1, and eliminating the results of the computations of the consolidation circuits for which the measurement sensors are malfunctioning; a first comparison means in each of the consolidation circuits, performing a comparison between the result of each computation means and the first result of the ordered storage means storing the computation results of the other computation means in the respective consolidation circuit to thereby detect a malfunctioning computation means; an ordered storage means for storing the results of each of the first comparison means ordering the results of each of the first comparison means in descending order of the indices associated with the consolidation circuits from i−1 to 1, and from n to i+1, and eliminating the results of the first comparison means of the consolidation circuits for which the computation means are malfunctioning; and a second comparison means in each of the consolidation circuits to compare the results of each of the first comparison means in one consolidation circuit with the result of one of the first comparison means others of the consolidation circuits to thereby detect malfunctioning first comparison means to shutdown the consolidation circuit for which the first comparison means are malfunctioning; means for hybridizing the inertial data and the radionavigation data; and means for hybridizing the inertial data and the anemo-barometric data.
