摘要
以鲁北测风塔工程沉桩施工为依托,初步总结GPS数据链天线发射端采用高增益天线在施工定位中的试验及应用情况,在进行远距离海上打桩施工时,完全可以采用高增益天线做GPS基准站无线电差分信号发射天线使用。该天线的使用效果能够满足稳定、连续、准确的GPS差分信号的发射和远距离传输。其有效工作距离能满足20～30km范围,初始化时间短,固定解的解算速度快,在控制网覆盖范围充分的情况下,可达到与近岸施工相当的精度效果,对类似工程的施工具有很好的借鉴和指导作用。
According to the examination and application, it posted the using of high-gain antenna in the radio difference-signal transmitting antenna of GPS base station that is viable during remote sea piling con- struction Engineering, taking Lubei anemometer tower penetration engineering as an example. The effect of antenna satisfied that GPS difference-signal transmitting stable, continuous and exact. The effective dis- tance is 20km^30km, and initialization short time, fixed solution calculating quickly, when coverage of control network is sufficient, accuracy is relate to coastal construction. It provides an instructive guidance to the related work.
