Further, a preset rule is preset for each reference station, and the preset rule specifically includes: and performing grouping processing on the generated observation data, preferably, grouping according to the attributes of the reference stations (such as the purposes, the geographic positions and the like of the reference stations), adding one same data subject to the observation data of the reference stations with the same attribute, adding corresponding data subject labels to the observation data according to the attributes of the reference stations after the observation data are generated, and then packaging. For example, a preset rule (grouping according to the use attribute of the reference station) is preset, each reference station follows the preset rule, each reference station groups observation data according to the use attribute thereof when generating the observation data, and when the use attribute of the reference station a is 1, the data subject label of the corresponding observation data is 1; when the application attribute of the base station B is also 1, the data subject label of the corresponding observation data is 1;
