摘要
FIELD: radio engineering, communication.;SUBSTANCE: in order to estimate an indication (11) of integrity of the system with respect to location errors (2) of very low probability, lower than or equal to about 10-7, the following steps are carried out in real time: measurement of data calculated by the system; calculation of a model of distribution H of location calculation errors (2) of the system; determination of parameters characterising the distribution model (H); modelling, in the probability domain, of the tail of the distribution H(x) by a calculation means as a function of said parameters applied to the extreme values theory; comparison in real time of the distribution of location errors with a tolerance threshold for providing an indication of integrity; and transmission in real time of the indication (11) of integrity of the system.;EFFECT: solving problems of estimating integrity margin of a satellite navigation system for malfunction events of very low probability.;7 cl, 3 dwg
