What does GNSS stand for?

GNSS stands for Global Navigation Satellite Systems. This term refers to a constellation of satellites that transmit signals to receivers on Earth, allowing users to determine their precise location, velocity, and time information. GNSS encompasses various systems, including the United States' GPS (Global Positioning System), Russia's GLONASS, the European Union's Galileo, and China's BeiDou, among others.

The significance of GNSS lies in its widespread application across various fields, such as aviation, maritime navigation, land surveying, and even for personal devices like smartphones, enabling precise navigation and timing functionalities. Therefore, understanding that GNSS is about global navigation via satellite technology is crucial for anyone engaging in electronic navigation practices.
