摘要
卫星定位的RTK-GNSS等高精度定位中FIX解的计算情况主要取决于实施地点的卫星配置、卫星数量、观测信息的质量和定位算法。卫星布局可通过导航消息进行估计,可视卫星数量和观测信息质量可通过模拟计算,考虑到周围建筑物等对信号的遮挡、反射和天线接收机的性能可以估计。本研究利用3d建筑物模型模拟预测了卫星定位观测信息的质量,并与实际观测信息进行了比较,还与高精度定位结果进行了比较,并与模拟进行了比较。研究了RTK-GNSS定位FIX状况预测的可能性。Abstract The Fixing of RTK-GNSS satellite positioning depends on Thesatellites' position, number of visible satellites,signal quality and positioning algorithm. The satellites' position can be calculated from Thenavigation messages,while the number of visible satellites and signal quality can be predicted using simulations takinginto consideration the multipath from surrounding buildings,antenna and receiver performance. In this paper,the signal quality is predicted using simulations with 3d buildings and compared with measured data。furthermore,simulated and measured RTK-GNSS positioning from signal quality are compared to evaluate thepossibility of using 3d buildings to predict the Fixing status of RTK-GNSS Positioning. theevaluation gives reasonable comparable results。
