Global Navigation Satellite Systems Engineering, Policy, and Design
One of the more popular sessions in recent years at the annual ION GNSS+ technical meeting is the panel discussion on a variety of satellite-based navigation systems, and it appears as if Chinese officials will have plenty of updates on its BeiDou navigation and positioning system to share.

China sent a new BeiDou navigation satellite into orbit on a Long March-3A rocket from the Xichang Satellite Launch Center, in the southwestern Sichuan Province, at 4:58 a.m., Tuesday, July 10.
The satellite is the 32nd of the BeiDou navigation system, and one of the BeiDou-2 family, which is the second generation of the system. The state-run Xinhua press agency confirmed the launch within two hours after liftoff.

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.

The R&S TS-LBS is a test system for testing GNSS and network-based LBS. Photo: Rohde & Schwartz.Rohde & Schwarz and MediaTek have successfully completed the verification of location based services (LBS) in the U-plane and C-plane for A-BeiDou (Assisted BeiDou), China’s GNSS satellite positioning system. The R&S TS-LBS test solution is designed to allow mobile manufacturers, chipset manufacturers, test houses and network operators to verify chipsets and mobile devices in order to obtain permission to operate them in a particular network.

China’s domestically produced satellite navigation system BeiDou has made significant progress in terms of its accuracy, according to reports out of China earlier this month. At a recent press conference, BeiDou engineers claimed that a new accurate positioning chip can now help users arrive at their destinations with an error margin of just one to two meters.

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.

Russia, which suffered a launch failure in July that cost it three GLONASS-M satellites, plans to launch four more by the end of this year and four more in the latter half of 2014 — part of an overall plan to place a total of 12 satellites into orbit by the end of 2015.
