  • Patent number: 10408970
    Abstract: A method of location of a device includes a displacement law containing a corrective factor of a bias combined by an arithmetical operation with a measured variable, and particles, each particle being associated with a current value of the corrective factor. The current value of the corrective factor being constructed at each iteration on the basis of a previous current value of the corrective factor, computed during a previous iteration, to which is added a random variable drawn according to a predefined probability law. The current values of various particles are initialized, before the first iteration, to various initial values, and during each iteration, for each particle whose coordinates are updated with the aid of this displacement law, the value of the corrective factor in the displacement law is taken equal to this corrective factor's current value associated with the particle.
