FIELD: physics, navigation.
SUBSTANCE: invention relates to satellite radio navigation systems. Said technical result is achieved by determining: a maintained position at a given moment, a maintained safe radius associated with the maintained position, the best position at the given moment, wherein the best position is: when data coming from an intermediate positioning device are available, the position associated with the best safe radius, wherein the best safe radius is selected by comparing, depending on a predefined selection criterion, an intermediate safe radius with the maintained safe radius, and when data coming from the intermediate positioning device are unavailable, the maintained position.
EFFECT: obtaining high-quality position data from the perspective of safe radius and availability, continuity of monitoring accuracy of the provided data.
