The GPS system is mainly composed of three parts, namely the space part, the ground monitoring part and the user part. The corresponding specific equipment is the GPS satellite constellation, the ground support system and the GPS receiver.

What are the applications of GPS measurement?According to different purposes, there are four basic ways to construct a GPS network。GPS networks have corresponding design guidelines. GPS point selection: It is mainly convenient for signal reception and uninterrupted and convenient for storage.

According to the status of the GPS receiver during positioning, GPS positioning can be divided into static positioning and dynamic positioning. The so-called static positioning means that the receiver is placed on the measuring station for several minutes to 1h or longer for observation to determine the three-dimensional coordinates (absolute positioning) of a point in the WGS-84 coordinate system, or two The relative position between the points (relative positioning). For dynamic measurement, at least one receiver is in motion, which is consistent with the principle of GPS positioning.
