Following the successful launch of the third-generation BeiDou satellites, ComNav Technology has been tracking and decoding the BD-3 satellite signals to provide better high-precision positioning services in the near future.

As the world’s fourth navigation satellite system, the construction of BeiDou satellite navigation network consists of three steps: experimental period from 2000 to 2003, regional coverage by 2012, and global reach by 2020.

On Nov. 5, 2017, the launch of two third-generation BeiDou satellites indicates that China has begun to upgrade its BeiDou Navigation Satellite System with global-coverage capabilities, according to the China Satellite Navigation Office.

The new-generation BeiDou satellites feature better accuracy, stability and signal clarity, thanks to improvements in laser communication devices, intersatellite links and atomic clocks.

Moreover, 18 third-generation BeiDou satellites will be launched by the end of 2018 to cover all nations involved in the Belt and Road Initiative. By the end of 2020, worldwide high-precision GNSS users are able to benefit from global reach of the third-generation Beidou system.

ComNav Technology has tracked and decoded the latest format BD-3 satellite signals: B1C and B2a from satellites Beidou-19 and Beidou-20.
