Global Navigation Satellite Systems (GNSS)
Global Navigation Satellite Systems (GNSS) are technologies that allow us to determine our precise location anywhere on Earth using signals from satellites orbiting the planet. These systems, such as GPS, GLONASS, Galileo, and BeiDou, transmit signals that are received by devices like smartphones and navigation systems. By calculating the time it takes for these signals to reach the receiver, GNSS can pinpoint an exact location in terms of latitude, longitude, and altitude. In geomatics geography, GNSS is essential for mapping, surveying, and conducting spatial analysis, enabling professionals to collect accurate geographic data.

Global Navigation Satellite Systems (GNSS) are networks of satellites that provide accurate positioning, navigation, and timing information to users on Earth. The most well-known example is the Global Positioning System (GPS). GNSS works by sending signals from satellites to receivers on the ground, which calculate their position based on the time it takes for the signals to arrive. This technology is used in various applications, including navigation for vehicles, smartphones, and aircraft, as well as in agriculture and mapping, enabling precise location tracking and improving safety and efficiency in many fields.
