China launches final satellite in system to rival American GPS

'Big Dipper' programme promises global navigation coverage

China has launched the final satellite in its Beidou constellation that emulates the US Global Positioning System (GPS), marking a further step in the country’s advance as a major space power.

The launch of the satellite onboard a Long March-3 rocket was broadcast live from the satellite launch base of Xichang, deep in the mountains of southwestern China, shortly before 10am.

About half an hour later, the satellite was deployed in orbit and extended its solar panels to provide its energy.

An initial launch scheduled for last week was scrapped after checks revealed unspecified technical problems.

The third iteration of the Beidou Navigation Satellite System promises to provide global coverage for timing and navigation, offering an alternative to Russia’s Glonass and the European Galileo systems, as well as America’s GPS.

The launch of the 55th satellite in the Beidou family shows China’s push to provide global coverage has been “entirely successful”, the system’s chief designer Yang Changfeng told state broadcaster CCTV.

“In actual fact, this also signifies that we are moving from being a major nation in the field of space to becoming a true space power,” Mr Yang said.

China’s space programme has developed rapidly over the past two decades as the government devotes major resources towards developing independent high-tech capabilities — and even dominating in fields such as 5G data processing.

The first version of Beidou, meaning “Big Dipper”, was decommissioned in 2012. Future plans call for a smarter, more accessible and more integrated system with Beidou at its core, to come online by 2035.

In 2003, China became just the third country to independently launch a crewed space mission and has since constructed an experimental space station and sent a pair of rovers to the surface of the moon.

Future plans call for a fully functioning permanent space station and a possible crewed flight to the moon, with its first attempt to send an orbiter and rover to Mars possibly coming as early as next month.

If successful, it would be the only other country besides the US to land on Earth’s closest planetary neighbour.

The programme has suffered some setbacks, including launch failures, and has had limited cooperation with other countries’ space efforts, in part because of US objections to its close connections to the Chinese military.
