GNSSalapú
GNSSalapú refers to systems, devices, and methods that rely on Global Navigation Satellite Systems to determine position, time, and velocity. The term encompasses technologies that use signals from multiple satellite constellations, such as GPS (USA), GLONASS (Russia), Galileo (EU), BeiDou (China), and regional systems like QZSS (Japan) or NavIC (India). GNSSalapú solutions are used in consumer devices, professional surveying instruments, and industrial applications.
Applications of GNSSalapú technologies are broad. They underpin navigation and mapping in smartphones and vehicles, enable
Priniciples and methods. A GNSSalapú receiver estimates the user’s position by processing signals from satellites to
Enhancements and standards. GNSS augmentation systems (EGNOS, WAAS, MSAS, etc.) improve reliability and accuracy. Data and
Limitations and vulnerabilities. Performance depends on satellite visibility and environmental conditions; obstacles, multipath, and atmospheric effects
