On 27th December 2011, Chinese officials confirmed that the country’s Beidou satellite navigation system was operational, albeit mainly in China, and on track to meet the goal of offering free, global coverage by 2020.

At a press conference, the China Aerospace Science and Technology Corporation said that Beidou is providing location data and SMS messaging using a network of ten satellites currently in orbit, and another six launches are planned for 2012.

Once fully operational, they should cover most of the Asia/Pacific region, and will form the backbone of a global system of over 30 satellites that should be in place by 2020.

According to Ran Cheng of China Aeriospace Science and Technology Corporation, the Beidou service would be free to all and said that the Chinese would be working on interoperability with the US GPS system, Russia’s GLONASS and the forthcoming EU Galileo network.

An initial version of the interface control documentation has been published online.

He said that the initial service was operating within 25 metres accuracy between 84 degrees to 160 degrees east longitude, 55 degrees south latitude to 55 degrees north latitude, at velocity accuracy of 0.8 metres per second and within 50 nanoseconds for timing.

Around 100,000 users are using the service so far, and accuracy will be brought down to 10 metres by next year.
