The "LRTK" is an innovative device that achieves centimeter-level precision positioning simply by attaching it to a smartphone or tablet, revolutionizing traditional field surveying methods. Despite its lightweight and compact design, the LRTK incorporates a powerful battery and high-performance antenna, making it capable of addressing various on-site requirements using only a smartphone. It supports single-point and continuous positioning, 3D point cloud scanning, soil volume calculations, and coordinate guidance. The device accurately records precise positional and orientation data concurrently with photography, facilitating real-time data sharing and centralized management through cloud integration.

By integrating augmented reality (AR) technology, the LRTK rapidly and accurately projects designs and planned structures onto physical sites. This significantly reduces human labor and construction timelines traditionally associated with alignment tasks. As a next-generation smart positioning solution, the LRTK greatly enhances operational efficiency and productivity across diverse fields, including civil engineering, construction, surveying, infrastructure maintenance, and disaster response. It contributes substantially to streamlining fieldwork and improving productivity in these critical sectors, providing a comprehensive, smartphone-based solution that meets the evolving demands of modern surveying and positioning tasks.
