The Global Positioning System (hereinafter referred to as GPS) to which the present invention is applied is a satellite positioning system that can cover all regions of the earth, also called a global positioning system or a global positioning system.

Such GPS was originally developed by the United States for military use, and its basic technology was developed for civilian use. Currently, GPS is being actively used in various fields. That is, it is applied to a wide range of fields such as providing simple location information, automatic navigation and traffic control of aircraft, ships, automobiles, collision prevention of oil tankers, precise surveying of large-scale civil engineering works, and mapping. It is developed variously.

The location information provided by the GPS can accurately calculate the current position by triangulating three different distances by measuring accurate time and distance from three or more satellites using a GPS receiver. Also, unlike compasses, satellite navigation systems can obtain not only three-dimensional information (latitude, longitude, altitude), but also speed, direction, and accurate standard time. Positional accuracy differs between military and civilian use. For civilian use, the horizontal and vertical error is about 10-15m and the speed measurement accuracy is 3cm per second. In addition, the satellite is equipped with three atomic clocks to provide time information with an error of 10 million minutes.
