GPS (Global Positioning System) geodetic refers to high-precision GPS positioning techniques used in geodesy, the science of measuring Earth's shape, orientation, and gravitational field. Geodetic GPS systems employ specialized receivers and techniques to achieve centimeter-level accuracy in positioning. These systems are crucial for various applications such as surveying, mapping, geophysical monitoring, and satellite positioning. They provide precise spatial reference points for a wide range of scientific, engineering, and navigational purposes.
