FIELD: radio engineering, communication.
SUBSTANCE: protection levels that are compared with the corresponding alarm limits are calculated horizontally and vertically to determine the integrity of the high-precision navigation definition of the user. The calculation of the protection levels is made taking into account the inaccuracy in the formation of satellite clock corrections and orbit corrections in the corrective information from the wide-band functional augmentation, the value of error variance of primary measurements introduced by the ionospheric and tropospheric refractions in the propagation of the signal from navigation spacecraft (NS), receiver noise and multipath.
EFFECT: increased reliability of high-precision navigation sightings in real time and reducing the time for the consumer to notify about the violation of the navigation integrity.
