GNSS stands for Global Navigation Satellite System. This terminology refers to a system of satellites that provide autonomous geospatial positioning with global coverage, allowing users worldwide to determine their exact location in terms of latitude, longitude, and altitude. GNSS encompasses various satellite systems, including the United States' GPS, Russia's GLONASS, the European Union's Galileo, and China's BeiDou. Understanding GNSS is essential for modern aviation as it enhances navigation accuracy, increases safety, and provides critical information for flight management and operations. The other options presented do not accurately represent the concept of GNSS or the specific technology involved in satellite navigation, making them less relevant in the context of aviation navigation systems.
