Satellite navigation is a technology that allows devices to determine their accurate location and time on Earth using signals from satellites . Receivers integrated in smartphones, cars, aircraft, and ships use these signals to compute their position and time, and display it on a digital map. This makes it possible to know where you are at every second and navigate from one place to another.
There are currently four global navigation satellite systems (GNSS): GPS (USA), Glonass (Russia), Beidou (China) and Galileo (European Union). Galileo is the most accurate of all.
Satellite navigation is everywhere
Satellite navigation is widely used in everyday life. It helps people find directions on their phones , and is used in many sectors, including transport, geodesy, construction, agriculture, drones, and scientific research. Satellite navigation provides also precision time, which is used for synchronizing critical functions of our modern societies, such as banking, energy grids and telecommunication networks.
