  • Device to aid navigation, notably inside buildings
    Patent number: 8812234
    Abstract: A device to aid navigation comprises: at least one inertial navigation unit; an integration module estimating the position, speed and orientation of the carrier on the basis of the data supplied by the inertial navigation unit; a digitized map of the locations in which the carrier moves, said map storing a navigable network along which the carrier may move; a module for generating position pseudo-measurements on the basis of the position estimated by the integration module and cartographic data supplied by the digitized map, a position pseudo-measurement indicating the position which should be estimated by the integration module in the presence of movement constraints imposed by the digitized map of the locations; an indirect extended Kalman filter connected to the module for generating position pseudo-measurements by a switch, said filter estimating the errors relating to the position, speed and orientation, and also any other variable associated with the inertial navigation unit, estimated by the integratio
