FIELD: physics, radio.
SUBSTANCE: invention relates to radio engineering and specifically to satellite navigation and can be used in a GNSS receiver. First data (5), indicating requirements of accuracy, continuity, integrity and availability of the system are determined, and second data (6), indicating the number of satellites in the constellation and the corresponding probabilities of failure, required in order to use a predetermined RAIM method for monitoring the system are determined. Third data (Pfa, Pmd) are acquired from the receiver for indicating the probability of false alarm and the probability of missed detection in accordance with the requirements, for the predetermined RAIM method, and a database (7) of these third data is created in accordance with predetermined scenarios. Data vectors are generated (2), which represent the radius of uncertainty concerning the distance of the receiver from the satellites, which can be determined by the receiver as a function of the first (5), second (6) and third (Pfa, Pmd) data. A database (9) of these vectors is created and a simulation of at least one of the scenarios on the basis of the vectors is executed.
EFFECT: high accuracy of predicting performance of a satellite navigation system owing to a large number of measured parameters, as well as the possibility of adapting prediction to different flight situations.
