Abstract:
The present invention relates to a method of determining an anomalous satellite in a multi-reference station environment and a determination apparatus using the method, which detect an anomaly in a satellite and determine the cause of the anomaly in a multi-reference station environment, and continuously provide services in an environment in which the cause of the anomaly is removed, thus improving availability and continuity, and enhancing an integrity monitoring function. A method of determining an anomalous satellite in a multi-reference station environment according to the present invention includes a first step of individually receiving satellite signals including code measurements and carrier measurements from one or more reference stations respectively communicating with a plurality of satellites, a second step of checking whether the number of reference stations communicating with the plurality of satellites is at least 3, based on the satellite signals, a third step of detecting presence or non-presence of an anomaly state of the satellites, based on the code measurements and the carrier measurements of the satellite signals if it is checked at the second step that the number of reference stations is at least 3, a fourth step of identifying an anomalous satellite from the anomaly state of the satellites detected at the third step, and a fifth step of determining a cause of an anomaly in the anomalous satellite identified at the fourth step.
