GNSStækni
GNSStækni, or Global Navigation Satellite System (GNSS), is a constellation of satellites providing signals from space that transmit positioning and timing data to GNSS receivers. The most well-known GNSS is the Global Positioning System (GPS) operated by the United States. Other notable systems include the Russian GLONASS, the European Galileo, and the Chinese BeiDou. GNSS technology enables precise positioning, navigation, and timing services for a wide range of applications, from everyday consumer uses like maps and location-based services, to critical infrastructure like aviation, maritime, and surveying. GNSS receivers calculate their position by determining the distance to multiple satellites using the time delay of the received signals. This process, known as trilateration, allows for accurate positioning even in remote areas where other navigation aids may be unavailable. The integration of multiple GNSS systems can further enhance accuracy and reliability, a concept known as augmentation. GNSS technology has revolutionized various industries by providing real-time, high-precision positioning data, contributing to advancements in transportation, agriculture, emergency response, and scientific research.
