China Launches Two BeiDou-3 Satellites Featuring Accurate Rubidium Atomic Clocks

According to reports out of China, new, very accurate rubidium atomic clocks onboard two BeiDou-3 satellites launched into space on November 5 have greatly improved the accuracy of the system.

The country launched two BeiDou-3 satellites into space via a single carrier rocket to support its global navigation and positioning network at 11:45 UTC on Sunday (November 5). The satellites were aboard a Long March-3B carrier rocket which took off from Xichang Satellite Launch Center in the southwestern province of Sichuan, according to the China Xinhua News Agency.

GPS, GLONASS, Galileo, and BeiDou for Mobile Devices

The navigation sensors for location-based services (LBS) are complex technical systems. Modern technical science can answer most questions about the optimality of particular position determination methods, signal processing algorithms, electronic circuits or similar well-defined problems, but the rigorous answer to the questions concerning the optimal LBS positioning sensor are still a big problem.
