China is now one satellite away from completing an orbiting network to rival GPS, with another successful launch in the country’s south on Monday.
The 54th and second-last of the constellation of the BeiDou navigation system was sent into a geostationary orbit by a Long March 3B carrier rocket from the Xichang Satellite Launch Centre in Sichuan province, southwest China, state news agency Xinhua reported on Tuesday.The report said space engineers overcame complications posed by the coronavirus epidemic to ensure the mission was accomplished.
The last of the 30 BeiDou satellites in the third-generation system is expected to be launched in May, three years after the first one went into orbit.
China’s completes core network of GPS rival Beidou with latest satellite launch
When completed, the network will be accurate to 10cm (3.9 inches) in China and Asia-Pacific, compared with the 30cm range offered by the US’ Global Positioning System (GPS).
BeiDou features have already been built into many popular smartphones, with processor chips such as Qualcomm’s Snapdragon and Huawei’s Kirin using the technology along with GPS and sometimes Europe’s Galileo and Russia’s Glonass systems, which allows access to as many satellite signals as possible.
Compared with its rivals, BeiDou has added services such as text messaging, enabling communications between users and the ability to trace users’ locations in emergencies……more here
