We would like to introduce high-precision satellite positioning as one of the key technologies to realize DX promotion. High-precision satellite positioning that grasps the exact position of people and things improves the quality and efficiency of operations. And now, centimeter-accurate high-precision satellite positioning has become a technology that anyone can handle. In this seminar, surveying will be used as an example as a solution using this high-precision satellite positioning. We will introduce from simple surveying that can be done by one person to wide range surveying by drone.
