초록

A system of GPS devices which receive civilian GPS signals and provide an intuitive graphical interface for displaying the relative position of GPS devices in relation to each other, the relative position being accurate to several meters and defined as the distance to, direction of and height variance between GPS devices. A first GPS device with the person or object to be located transmits its GPS determined location to a second GPS device. This second GPS device includes a means for receiving the GPS determined position of the first GPS device, and also...
