A large number of practices and researches show that in an outdoor environment, the installation height of a signal receiving line has a significant influence on the GPS signal receiving effect. Since the GPS signal is blocked and interfered by ground obstacles such as buildings, trees, terrain undulations and the like during propagation, the higher the installation position, the less the signal receiving line is blocked and interfered, thereby improving the strength and stability of the signal, and therefore, in order to obtain better GPS signals, when performing surveying and mapping work outdoors, it is usually desired to install the signal receiving line as high as possible.
