Abstract
The invention relates to a calculation device providing means for estimating an indication of integrity of a satellite navigation system, including a means for estimating in real time, by measuring data calculated by the navigation system, an indication of integrity of the system with respect to very low-probability location errors, the device including a means for receiving data calculated by the location system, a means for estimating a model of distribution of location errors, a means for estimating parameters characterizing the distribution model, a calculation means applying the extreme values theory as a function of the parameters characterizing the distribution model enabling the modeling of the distribution of very low-probability location errors, a means for estimating in real time an indication of integrity for very low-probability location errors, and a means for transmitting in real time an indication of integrity.
