An advanced BeiDou navigation satellite spreads its high-efficiency solar wings in geostationary orbit high above planet Earth. Intricate phased-array antennas beam precise atomic clock time signals down through the blue upper atmosphere to guide cargo ships, aircraft, and smart devices across the globe.

Originating in the year 2000 and reaching full global constellation capability in 2020, China's BeiDou Navigation Satellite System (BDS) is one of the world's four major global satellite navigation networks alongside GPS, GLONASS, and Galileo. BeiDou uses rubidium atomic clocks to provide accurate positioning, timing, and search-and-rescue services worldwide.
