<p>The method involves calculating a proportion of distribution of samples (1-3) to verify that a protection radius (XPL) is lower than a threshold of alarm (J) and a quotient of the radius, and an estimated location error (XNSE) is less than an estimated error requirement level. A component of the distribution of the samples is modeled, where the component represents the samples with low probability of occurrence of the distribution, and modeling is calculated by application of an extreme value theory from the samples observed from the distribution. An independent claim is also included for a system for calculating low probability events for evaluating precision performance of a satellite navigation system.</p> |
