High-tech radar will also improve nation's ability to forecast, warn of natural disasters, experts say
China is putting its nearby waters under more effective surveillance with its newly operational high-tech satellite.
Launched on Wednesday morning, the Gaofen 3 high-resolution Earth observation satellite will help the nation beef up its capabilities to safeguard its maritime interests and to help forecast and warn of natural disasters, space program officials said.
The satellite was delivered by a Long March 4C rocket that blasted off from the Taiyuan Satellite Launch Center in Shanxi province.
It is equipped with a radar system that captures images from space with a resolution down to 1 meter, according to the State Administration of Science, Technology and Industry for National Defense, which oversees China's space programs.
The Gaofen 3, which was developed by the China Academy of Space Technology in Beijing, is capable of generating radar images in all weather conditions and can work around the clock.
The satellite will play an important role in monitoring the marine environment, islands and reefs, and ships and oil rigs, said Xu Fuxiang, head of the Gaofen 3 project at the academy.
He said that considering China has a total of 32,000 km of coastline, 380,000 square kilometers of territorial seas and more than 6,500 islands that have an area of at least 500 square meters, satellites like the Gaofen 3 will be very useful in safeguarding the country's maritime rights and interests.
The Gaofen 3 will also help in disaster forecasting, assessment and relief, which now heavily rely on imported satellite data, Xu added.
Gaofen 1 was sent into space from the Jiuquan Satellite Launch Center in April 2013. Four other Gaofen satellites were launched in 2014 and last year.
The Gaofen 5, 6 and 7 will be optical remote sensing satellites and are under development, according to the State Administration of Science, Technology and Industry for National Defense.
