GPS (Global Positioning System) consists of 24 satellites in orbit. With appropriate receiving equipment the system can be used to determine geographical co-ordinates such as position and height. There are many uses of GPS including navigation, mapping, surveying, and monitoring.
This Open Directory Category is for GPS sites that relate to Geomantics, that is the study and measurement of the physical environment of the earth.
