Which satellite navigation system is associated with Japan?

• A. GALILEO
• B. NAViC
• C. QZSS
• D. BeiDOU

Answer: (C)

The correct answer is associated with Japan's satellite navigation efforts, specifically the Quasi-Zenith Satellite System (QZSS). This system is designed to enhance the accuracy and reliability of GPS (Global Positioning System) using satellites that are positioned in orbits which provide better coverage in urban canyons and mountainous regions of Japan. QZSS improves the availability of positioning services, especially in areas where traditional GPS signals can be obstructed or weakened. The other satellite systems mentioned serve different countries or regions. GALILEO is the European Union’s satellite navigation system, NAViC is specifically an Indian navigation system, and BeiDou is China's satellite navigation system. Each of these systems operates independently and serves distinct geographical and operational needs.
