Application case sharing of static positioning measurement principles in the engineering field
Abstract:
In the engineering field, accurate positioning measurement is essential for project planning and design and construction are crucial. The static positioning measurement principle is a common measurement technology that can provide high-precision position information. This article will share an application case of static positioning measurement principles in the engineering field, and attach corresponding code examples.
First, the engineering team selected three ground measurement and control points (A, B, and C) in the bridge construction area and measured these points using traditional measurement equipment (such as a total station). The engineering team then used GNSS receivers to conduct static observations of ground measurement and control points and obtained the initial coordinates of these points.
Next, the engineering team input these initial coordinates into the algorithm based on the static positioning measurement principle for processing, and obtained high-precision coordinate information for the bridge construction area. This coordinate information will be used to determine the location and orientation of the bridge's main structure and ensure the bridge's precise layout.
During the construction process, the engineering team will regularly observe the coordinates of ground measurement and control points and use static positioning measurement principles for precise positioning. In this way, they can detect small changes in the bridge position in time and adjust them to ensure the accuracy of bridge construction.
