Global Navigation Satellite System (GNSS):
The Global Navigation Satellite System (GNSS) is a global positioning and navigation system that provides real-time and accurate geospatial information. It is comprised of a constellation of satellites orbiting the Earth, ground-based control stations, and user receivers. The most well-known GNSS is the Global Positioning System (GPS), but there are other systems like GLONASS, Galileo, and BeiDou.
GNSS technology allows users to determine their precise position and time, making it essential in various applications such as navigation, surveying, agriculture, disaster management, and more. GNSS receivers receive signals from multiple satellites, allowing them to triangulate the user's location. The accuracy of GNSS varies based on factors like signal obstructions and the number of
