Designers: Beidou progressing at rapid pace

The first ground-based augmentation system to improve the performance of the Beidou Satellite Navigation System developed by China was approved and accepted in March in Wuhan, Hubei province.

The general index of the system's precision reached "an international advanced level", according to an evaluation committee led by Sun Jiadong, an academician with the Chinese Academy of Sciences and chief designer of the Beidou system.

Consisting of 30 ground tracking stations, an operating system and a precision positioning system, the augmentation system will significantly improve the accuracy and reliability as well as reducing the positioning time of Beidou, said Liu Jingnan, an academician of the Chinese Academy of Sciences from Wuhan University.
