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.
