摘要
结合一例航测工程实践,从不同的角度对精密单点定位(PPP)应用于GPS辅助航测的可行性进行了分析。结果表明,PPP的动态定位结果同双差解的符合精度达到cm~dm级,而且将PPP的解算结果应用到GPS辅助空中三角测量中,也取得了同双差方法相当的精度。因此,PPP应用于GPS辅助航空摄影测量中切实可行。
Based on an Aerial Photogrammetry engineering practice, this paper made a feasibility analysis on the application of PPP in GPS-supported Aerial Photogrammetry from different angle. The result showed that the contrast precision between the PPP solution and double-differenced solution achieved cm- dm level and using the result of PPP in GPS-supported aerial triangulation can got comparative precision compared with the double-differenced solution. Therefore, the application of Precise Point Positioning in GPS-supported Aerial Photogrammetry is feasible.
