Description

Technical Field

[0001] The utility model belongs to the technical field of deformation monitoring, and in particular relates to a single-layer prism and GNSS coaxial supporting structure. Background Art

[0002] During deformation monitoring, it is necessary to ensure that the relative coordinates of the geodetic space positions of the GNSS antenna and the observation prism are fixed and unchanged and have a coaxial and concentric geometric spatial relationship of a stable plumb bob. The prior art usually sets the GNSS antenna on the shell of the prism, such as Chinese patent CN 217589434 U, which sets a GNSS antenna fixing rod by opening a hole in the protective cover. However, this installation method is difficult to determine because the center of the protective cover and the center of the prism do not necessarily coincide, and its position is difficult to determine. Even if it can be determined, the shell will be easily deformed due to impact during later use, resulting in loss of accuracy. Utility Model Content
