METHOD AND SYSTEM FOR DETERMINING PROTECTION LIMITS WITH INTEGRATED EXTRAPOLATION OVER GIVEN TIME HORIZON Russian patent published in 2015 - IPC G06F17/16 G01S19/20 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A method for determining protection limits at a future moment associated with navigation parameters of a bearer, including estimating the navigation parameters of the bearer at the present moment, developing a statistical model of the estimation errors of navigation parameters of the bearer at the present moment in the form of a covariance matrix, extrapolating, for a future moment, the statistical model of the estimation errors, calculating protection limits at the future moment from the extrapolated statistical model, wherein the extrapolation of the statistical model of the estimation errors implements the application of a constant positive transition matrix to a standard deviation vector constructed from the square root of the elements of the diagonal of the covariance matrix, in order to propagate, up to the future moment, the standard deviations of the navigation parameters developed at the present moment, wherein said propagation is independent of the previous behaviour of the bearer.

EFFECT: easy determination of protection limits using integrated extrapolation of the protection limits.
