Abstract: An ambiguity of whole cycle determination method, apparatus and system, a movable device (112) positioning method, apparatus and system, a movable device (112), and a base station (111). The ambiguity of whole cycle determination method comprises: a movable device (112) acquires first carrier phase observation data, and receives second carrier phase observation data sent by a base station (111) (S101); determine inertial navigation location data as first location data (S103); determine an estimator of the ambiguity of whole cycle of a satellite frequency point according to the first location data and the observation data (S105); and determine the ambiguity of whole cycle according to the estimator (S107). By using the processing approach, the ambiguity estimator is constructed on the basis of the inertial navigation location and the carrier phase observation value, and the ambiguity is fixed according to the estimator, which achieves an INS-aided RTK fixed ambiguity approach. In this way, on the one hand, this makes it unnecessary to carry out ambiguity search, which can avoid an error of the fixed ambiguity solution caused by the convergence of the ambiguity search caused by an error of the carrier phase observation value to a local minimum. On the other hand, a pseudorange observation value is not used, which can avoid an error of the fixed ambiguity solution caused by the pseudorange being affected by errors such as the multipath effect in the harsh environment. Therefore, the robustness and the efficiency of ambiguity fixing can be effectively improved, thereby achieving fast and accurate positioning of the movable device (112).
