摘要：

By analyzing the geometrical relationship between wide-lane ambiguity, geo-free model and ionosphere-free model, a method of fixing integer ambiguity between base stations in network RTK and the corresponding test method are presented. The ambiguities of wide-lane are fixed through MW-combination first and regarded as truth value, and then the floating resolution of the ambiguities of L1 and L2 is gotten by adjustment calculation combined with the models of geo-free and ionosphere-free at single epoch. After that the floating ambiguities are rounded to the nearest integers directly. Finally, the correctness of ambiguities is checked through the short and long GPS/BDS baselines. The result indicates that this method can fix ambiguities of network RTK fast and steadily. Additionally, it is effective to both short and long baselines.
