Abstract
A method for achieving inertial localization of a carrier using a stochastic filter of recursive-Bayesian type implemented by an inertial localization device, the method including a plurality of cycles, each cycle including a propagation procedure and, when a measurement is available, an updating procedure, in which method, in the propagation procedure, the propagation is performed using a propagation model taking into account at least one component of a matrix of the spatial gradients of the gravity vector, which matrix is delivering using an enriched gravimetric model.
Claims10
A method for inertially localising a carrier using a recursive Bayesian type stochastic filter implemented by an inertial localisation device, the method comprising a plurality of cycles, each cycle comprising a propagation step and an update step, wherein, during the propagation step, propagation is performed using a propagation model taking at least one component of a spatial gradient matrix of the gravity vector provided by an enriched gravimetric model into account.
