-board digital equipment.
1. Global Positioning System (GPS): The most renowned example of satellite navigation is the American-owned GPS. It starts transmitting radio signals which are received by digital equipment like smartphones, GPS devices in cars, and specific trackers.
2. GLONASS: GLONASS is Russia's equivalent to the GPS, providing real-time position and velocity determination. People who lose their path in the wilderness or remote areas are found using this network, as it consistently broadcasts radio signals back to Earth.
3. Galileo: This is Europe’s global navigation satellite system, providing a highly accurate global positioning service. It has been used for accurate mapping, and in automated cars and drones for navigation and control.
4. BeiDou: It is a satellite navigation system developed by the Chinese government. It's often used for civilian purposes like navigation for vehicles and ships, precise time-keeping, and disaster relief efforts.
5. IRNSS: Stands for Indian Regional Navigation Satellite System, it's an Indian-based satellite navigation system. IRNSS functions like GPS, but it covers only India and the region around it. It's used for accurate mapping, terrestrial, aerial and marine navigation.
