Technical Field
[0001] The utility model relates to the technical field of surveying and mapping, in particular to a total station device with a self-contained positioning system. Background Art
[0002] In the current surveying and mapping field, RTK technology and total station are the two main surveying tools. RTK excels in point positioning with its high precision and real-time performance, while total station occupies a place in field surveying with its versatility and high-precision measurement.

The traditional field surveying process usually uses RTK (real-time kinematic differential) technology to locate points first, then determines the coordinates based on the points and elevations, and finally uses a total station for measurement. Although this process is mature, it still has problems such as inconvenient equipment to carry and complicated operation. Therefore, this application proposes a total station device with a positioning function that is both portable and easy to use. Utility Model Content
