The present invention relates to a method for determining an abnormal satellite in an environment having multiple reference stations, and to a determining apparatus using same, the method and apparatus involving detecting the abnormality of a satellite in the environment having multiple reference stations and determining and eliminating the cause of the problem so as to continuously provide a service in the environment with no abnormality, thus improving availability, continuity and integrity monitoring function. The method for determining an abnormal satellite in an environment having multiple reference stations according to the present invention comprises: a first step of receiving satellite signals including a code measurement and a carrier wave measurement, respectively, from one or more reference stations which communicate with multiple satellites, respectively; a second step of checking, from the satellite signals, whether the number of reference stations which communicate with the multiple satellites is at least 3; a third step of detecting, if it is verified in the second step that the number of reference stations is at least 3, whether or not the satellite is in an abnormal state, on the basis of the code measurement and the carrier wave measurement; a fourth step of identifying an abnormal satellite on the basis of the abnormal state of the satellite detected in the third step; and a fifth step of determining the cause of the problem with the abnormal satellite identified in the fourth step. |
