The Chinese Beidou satellite navigation system is almost finished, thanks to the launch of a new satellite this week.
China launched its 54th Beidou satellite on a Long March 3B rocket on Monday (March 9). The rocket lifted off from the Xichang Satellite Launch Center in southwest China at 7:55 p.m. local time (7:55 a.m. EDT; 1155 GMT). Footage from state media outlet CCTV showed a flawless night liftoff as the satellite rocketed into space, en route to geosynchronous orbit.
In a speech broadcast on CCTV, Yang Changfeng, chief designer of the Beidou Navigation Satellite System, said the satellite series is using advanced technologies such as artificial intelligence and blockchain, which links blocks of data together using cryptography.
"We have focused on constantly developing the Beidou system's new application modes and new business forms, as well as its integration with the new economy," Changfeng said in the speech, which was delivered in Chinese and translated by CCTV.
The China Aerospace Science and Technology corporation declared the launch "a complete success" and said a final launch in May will complete the constellation, according to a statement translated into English using computer translation.
The satellite series, which is China's equivalent to the Global Positioning System (GPS) in the United States, will use satellites in a range of orbits. Sectors that will use the Beidou system include public security, power, disaster reduction, smart cities, fishing and transportation, according to SpaceNews. Beidou can also be used by the People's Liberation Army for weapons guidance and targeting, among other things.
Chinese social media users shared images and information about the launch before it was announced by Chinese state media, SpaceNews added, noting that villages in "drop zones" (where spent rocket stages fall to Earth) were told a little ahead of time in case an evacuation would be necessary. Xichang launches can pose a threat to inhabited areas; in November 2019, another Beidou launch on a Long March 3B rocket ended with booster segments crashing into a settlement downrange.
CCTV footage showed the workers taking extra health precautions during preparations at Xichang, including wearing face masks. The novel coronavirus has made its mark in China, where the bulk of the world's nearly 130,000 reported cases are located. That said, the World Health Organization notes cases in China are declining, and it says the pandemic can be contained in other countries as long as proper measures are taken.
A report in China's Global Times on Monday suggests most areas of the Chinese space industry have avoided severe disruption from coronavirus, except for the virus' epicenter in Wuhan.
