GPS动态后处理技术在超高层建筑施工中的应用
|
摘要
GPS动态后处理技术是利用GPS进行建筑测量的作业模式之一,其采用快速求解全周期模糊度的技术,通过先进的内业处理软件进行平差求中误差,可将精度提高到毫米级。PPK测量模式作业半径可达50 km,不需要在基准站与移动站间传输数据,也不需电台实时传输,数据均为事后处理,而且测量周期短,可满足超高层建筑施工中的结构健康监测和轴线控制网的检核。
The GPS dynamic post-processing technology is one of operational modes for building measurement by using GPS.It adopts the technique of quickly solving the whole cycle ambiguity and adjustment error can be improved to millimeter level by the advanced internal processing software to adjust the root mean square error.The PPK measurement mode has a working radius of up to 50 km.It does not need to transmit data between the base station and the mobile station,nor does it need to be transmitted in real time.The data are all post-processed and its measurement cycle is short,which can satisfy the structural health monitoring and check the axis control network check in super highrise building construction.
