Gps tracker application
In the field of engineering survey, GPS static relative positioning technology is used to deploy precision engineering control networks for precision monitoring of land subsidence monitoring in cities and mining areas, dam deformation monitoring, high-rise building deformation monitoring, and tunnel penetration measurement. Encrypted mapping control points, using GPS real-time dynamic positioning technology (RTK) mapping various scale topographic maps and for construction stakeout.
In the field of aerial photogrammetry, China's surveying and mapping workers also applied GPS technology to various stages of aerial surveying, such as aerial surveying and field control surveying, aerial photography flight navigation, and airborne GPS aerial surveying.
In terms of geodynamics, GPS technology is used for global plate movement monitoring and regional plate movement monitoring. China has begun to use GPS technology to monitor the Antarctic plate movement, the Qinghai-Tibet Plateau crustal movement, Sichuan Xianshuihe crust fault movement, and established the China crustal deformation observation network, the Three Gorges reservoir deformation observation network, the Metropolitan GPS deformation monitoring network. GPS technology has been used for marine surveying and underwater terrain mapping.
