| 摘 要： | 在建筑物变形监测中,嵌入GPS实时动态(Real-time Kinematic,RTK)方法的普通双频RTK接收机不能应对基线较长且电离层比较活跃的情况。因此,提出一种基于无电离层三差观测量的扩展Ka1man滤波模型,并通过试验与普通RTK接收机进行比较,证明了其可行性。

| Abstract: | In the deformation monitoring of buildings,the utilization of common dual frequency receivers in the method of Real-Time Kinematics(RTK),Global Positioning System(GPS) cannot accommodate the case that the baseline is long and the ionosphere is active.Therefore,an extended Kalman filter model based on the triple-differenced ionosphere-free method is proposed and through the tests,the model is compared with the common RTK receivers and is proved to be feasible. |
