China now has five navigation-and-positioning satellites, the launch of the fifth Beidou satellite took place in April. The system provides regional coverage of China and surrounds. It is named Beidou after the group of seven stars (Septentrio is Latin for ‘north') of the constellation Ursa Major, known in many cultures under different designations, in the UK ‘The Plough', ‘Big Dipper' in the US and ‘Big Mother Bear' in Russia. Others see the constellation as resembling a wagon. The first Beidou satellite (1A) was launched on 30th October 2000 followed by 1B on 20th December 2000. Since 2001 China's army and... (read more)

Beidou Satnav System Operational

On 27th December 2011, Chinese officials confirmed that the country's Beidou satellite navigation system is now operational, albeit mainly in China, and on track to achieve 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...

BeiDou Maturing Rapidly

Development and Status of BeiDou Navigation Satellite System
The BeiDou Navigation Satellite System (BDS) officially started providing its service to the Asia-Pacific region on 27 December 2012. Its regional service capability is equal to that of GPS. As the third global navigation satellite system, BDS has attracted considerable attention around the world, and the orbiting satellites and ground stations continue to work well. Technical evaluations and practical tests involving various user devices have proved that the BDS is functioning as designed, and in line with requirements. China regards BDS as an important driving force, representing new opportunities for the GNSS and LBS industries, and is keen to promote... (read more)

NovAtel Announces Beidou Support

Canadian manufacturer of GNSS products NovAtel has added support for the BeiDou Navigation Satellite System (BDS) to its OEM6 family and selected OEMStar GNSS receivers. The long anticipated BDS Interface Control Document (ICD) release marks a significant milestone that facilitates global acceptance of BeiDou into the growing range of satellite-based positioning applications. NovAtel has a long-standing partnership with several Chinese GNSS system manufacturers. This partnership has allowed NovAtel to verify B1 and B2 signal tracking on its latest generation receivers. The company has been supplying GNSS receivers that include the BeiDou constellation since Q4 2010. Pat Fenton, CTO at NovAtel,... (read more)

China Announces Worldwide Coverage by BeiDou

At the end of 2018, China’s Satellite Navigation Office announced that the country’s GNSS (called BeiDou or ‘BDS’) is now available as a global service. Originally, worldwide coverage was not expected to be achieved until 2020, but this early completion of the system means that China now joins the USA’s GPS, Europe’s Galileo and Russia’s GLONASS as the only four global providers of satellite-based positioning, navigation and timing (PNT) services. Ran Chengqi, director general of the China Satellite Navigation Office, is quoted as saying that BeiDou has “officially entered the global era as [it] expands from a regional system to... (read more)

Beidou Network Now Open for Commercial Use

China has opened up its domestic Beidou GPS substitute for commercial use across the Asia-Pacific region. Up until now, use of the satnav network had been restricted to the Chinese military and government. China intends to make Beidou available worldwide by 2020. The China Satellite Navigation Office says Beidou can identify a user’s location to 10 metres, their velocity within 0.2 metres per second, and clock synchronisation signals to within 50 nanoseconds. At the moment, six satellites are in orbit, and it has been reported that at least 40 more will be added to the system over the next years.... (read more)

BeiDou Focus at China Satellite Navigation Conference

The Chinese satellite navigation community came together from 15 to 17 May 2013 at the International Exhibition & Convention Center in Wuhan, China, for the 4th China Satellite Navigation Conference (CSNC). The extensive programme of presentations was accompanied by a large trade show running in parallel. The theme of this year's conference was 'BeiDou Applications - Opportunities & Challenges', which obviously paid a lot of attention to the new Chinese satellite navigation constellation. The conference attracted around 1,500 attendees, most of whom came from China although some delegates travelled from abroad. There were many familiar faces among the manufacturers showcasing...

ComNav and CGEOS Build First BeiDou CORS Station in Europe

Recently, the first European BeiDou CORS station – QIAO CORS Station – was built in Wallonia, Belgium, by the ComNav local partner CGEOS. 'Qiao' means 'bridge' in Chinese and Joël Van Cranenbroeck, managing director of CGEOS, is working to build a bridge between the Chinese and European GNSS industries by introducing ComNav's high-precision Chinese GNSS technologies to European users. The QIAO station can track BeiDou Navigation Satellite System on the three frequencies and transmit observation data in RTCM format in real time through NTRIP (Networked Transport of RTCM via Internet Protocol) and observation data in RINEX format, a data interchange format...
