Beidou Navigation Satellite System consists of how many satellites?

• A. 24
• B. 28
• C. 35
• D. 40

Answer: (C)

Beidou’s global navigation capability comes from a deliberate constellation size that ensures reliable, worldwide coverage. The final BeiDou-3 constellation numbers 35 satellites: 27 in Medium Earth Orbit, 5 in inclined geosynchronous orbits, and 3 in geostationary orbit. This mix provides diverse line-of-sight geometry, improves redundancy, and supports accurate positioning and timing around the world. The other options don’t fit because Beidou uses 35 satellites in its global system, not 24, 28, or 40.
