| 摘 要： | 提出了一种适用于GPS多参考站网络的RTK模糊度固定方法. 首先, 以参与模糊度解算的参考站三角形重心为参考点, 将与其形成高度角最大的卫星选作参考卫星, 进而提供了载波观测值权阵构造的参数以及模糊度网解正确性的检验条件. 然后, 通过双频线性观测数据组合计算双差宽巷模糊度, 并利用无电离层观测数据组合计算L1模糊度浮点解, 引入卡尔曼滤波进行精化, 并实时估计对流层延迟参数. 最后, 通过Z变换对模糊度协因素阵进行去相关, 从而减小模糊度整数解的搜索空间, 提高LABMDA算法固定模糊度的效率. 实验结果表明, 该方法能在40个历元内可靠实现多个参考站间整周模糊度解算.

| Abstract: | A method for integer ambiguity resolution in the global positioning system (GPS) multi-reference station network real time kinematic (RTK) is proposed. First,the barycenter of the triangle of reference stations for ambiguity resolution is taken as a reference point. The satellite which has the largest elevation angle with the reference point is selected as a reference satellite. The parameters for constructing the weight matrix of carrier phase observation and the criteria for checking the correctness of in... |
