GNSS (Global Navigation Satellite System) is better than GPS because it encompasses multiple satellite systems, not just the U.S. GPS. It combines satellites from GLONASS (Russia), Galileo (EU), and BeiDou (China), providing greater accuracy, reliability, and global coverage. This multi-constellation approach ensures better signal availability and accuracy, especially in challenging environments such as urban areas or dense forests, enhancing navigational precision for various applications.
