What technology is commonly used for Global Positioning System (GPS) navigation?

The choice of satellite technology is correct because GPS relies fundamentally on a constellation of satellites that transmit signals to GPS receivers on the ground. These satellites are positioned in such a way that at any given time, multiple satellites are visible from any point on Earth. The GPS receiver determines its location by calculating the time it takes for signals from these satellites to reach it, through a process known as trilateration.

The satellites continuously broadcast information regarding their position and the exact time the signals were sent, allowing the receiver to triangulate its own position by comparing the messages received from multiple satellites. This system enables pinpoint accuracy in navigation, which is essential for applications ranging from everyday route navigation to advanced military operations.

Options like optical technology, wireless communication technology, and geothermal technology do not play a role in GPS navigation. Optical technology pertains more to visual line-of-sight measurements, wireless communication technology does not specifically relate to satellite positioning, and geothermal technology relates to energy derived from the Earth’s internal heat, which is unrelated to GPS systems.
