Frequently Asked Questions
What is China's Beidou Navigation System?
Beidou (BDS) is China's global navigation satellite system with 45 satellites providing positioning, navigation, timing, and short message communication services. It offers global coverage with 10m positioning accuracy, regional coverage with 1m accuracy, and centimeter-level accuracy with ground augmentation.
How does Beidou compare to GPS?
Beidou provides comparable positioning accuracy to GPS (10m globally) but adds unique features: short message communication (up to 1,000 characters via satellite), dual-frequency signals for better urban accuracy, and Asia-Pacific enhanced coverage. Beidou is interoperable with GPS, and most modern smartphones support both.
How many people use Beidou?
Beidou serves over 1 billion users globally. In China, Beidou is the primary GNSS for government services, transportation, and agriculture. Internationally, Beidou has users in 230+ countries, particularly in Belt and Road Initiative partner nations.
Can Beidou work without internet?
Yes. Beidou's short message communication feature allows text messaging via satellite without cellular coverage. Basic positioning also works offline using only satellite signals. This makes Beidou essential for maritime navigation, wilderness rescue, and military operations.
What companies make Beidou chips?
UniStrong (北斗星通) is the largest Beidou chipmaker. Other key players include Unicore Communications (high-precision RTK), Allystar (low-power IoT chips), ZTE Microelectronics (smartphone chips), and Tsinghua Unisplendour (multi-GNSS baseband chips).
