BEIJING, China announces plans to build global high precision enhancement system based on Beidou

At the International Symposium on "The opportunities and challenges faced by the international application of Beidou", Beijing's all-public think strong announced plans to build a global high-precision enhancement system based on Beidou.

When the system is completed, the positioning accuracy of Beidou system will be upgraded from 10 m to centimeter, and the global operation is covered. The system is named "Chinese precision" (China CM), based on the Beidou system, "China precision" will provide the global users with a completely free meter-level precision free open service, as well as decimeter-level, CM-level precision value-added licensing services.

At present, Beidou has less than 1% global market share, system precision and GPS, technical index advantage is not obvious, with 20 years of history and accounted for more than 99% of global market share of the GPS system competition is very difficult. If the Beidou can set up the "China cm precision" system as soon as possible, it will be a low investment to overtake the Beidou corner, forming a north-dominated, compatible GPS and other systems of the global satellite navigation market new pattern.

"Chinese precision" is based on the Beidou High Precision Enhancement Service system, has the broad market prospect. 2010 Global Satellite Navigation application market size of 76.7 billion U.S. dollars, according to industry experts predict the 2010-2020 market size of the annual composite growth rate of more than 10%, 2020 will reach 220 billion U.S. dollars, in which high-precision applications can reach the overall market of 1/4, that is, 50 billion U.S. dollar market capacity.

Guo Xinping, chairman of the public, said the company invested 300 million yuan in the construction of "China precision" service system, the use of self-research receivers and antennas in the domestic and overseas synchronization set up a global reference station network, input expert technical team, in 2014 began the global Reference Station network construction, 2015 to achieve meter-level precision (1-2 meters) free service, 2016 to achieve decimeter-level precision licensing services to 2017 to achieve a centimeter-level precision licensing services.

According to the briefing, hemisphere GNSS, a wholly-owned company, has created and operated the world's first L1 based differential enhanced data service system, "Satloc", which has incorporated the leading scientists who have built international commercial high-precision enhanced service systems, In the wide area difference error algorithm and receiver difference algorithm, the company also has long-term technology accumulation, has serialized antenna, chip, receiver and terminal products.
