What is the Beidou system?

• A. US-based military communication satellite network
• B. China's global navigation satellite system
• C. Chinese weather satellite constellation
• D. Russia's navigation system

Answer: (B)

Beidou is China’s global navigation satellite system, providing positioning, navigation, and timing services to users around the world, much like GPS does for the United States. It grew from regional coverage to full global reach with Beidou-3, using a mix of satellites in geostationary, inclined geosynchronous, and medium Earth orbits to ensure worldwide availability. The system is operated by Chinese agencies and serves both civilian and military users, offering open service for general use and additional authorized services. It’s not US-based, not a weather satellite constellation, and not Russia’s navigation system.
