Global Navigation refers to the methods and technologies used to determine one's position anywhere on Earth. It often relies on systems like the Global Positioning System (GPS), which uses satellites to provide accurate location data. This technology is essential for various applications, including aviation, maritime navigation, and personal navigation devices. In addition to GPS, other systems such as GLONASS from Russia, Galileo from the European Union, and BeiDou from China contribute to global navigation. These systems work together to enhance accuracy and reliability, allowing users to navigate efficiently across different terrains and environments worldwide.
