Satellites to monitor country鈥檚 gas pipes
Print Edition
CHINA is planning to use its domestically operated satellite navigation system to help log and detect possible leaks in gas pipelines, the National Administration of Surveying, Mapping and Geoinformation said yesterday.
The program, which uses the BeiDou Navigation Satellite System (BDS), is already operational in “at least 10 cities” and will be in place in more than 100 “soon,” the agency said in a statement.
China’s 400,000 kilometers of urban gas pipelines are fitted with pressure transistors that indicate low pressure or potential leaks. However, they can’t be used to identify the exact site of the problem.
Under the new system, gas engineers will be given hand-held devices to accurately record the locations of faults, said Miao Qianjun, secretary-general of the Global Navigation Satellite System and Location Based Services Association of China.
“The data collected will be used to provide real-time risk assessment,” Miao said.
“The devices will also track the movements of employees, ensuring their productivity,” he said.
The government plans to expand its urban gas pipeline network to 600,000km by next year.
China’s first BDS satellite was launched in 2000 to provide an alternative to foreign systems. In 2012, it began providing positioning, navigation, timing and short message services to China and some parts of the Asia-Pacific region.
