China launches high-resolution Earth observation satellite

What in news:

·       China launched Gaofen-11, an optical remote sensing satellite, as part of the country's high-resolution Earth observation project.


·       The Gaofen-11 satellite was launched on a Long March 4B rocket at 11 am Beijing Time from the Taiyuan Satellite Launch Center in northern Shanxi Province.

·        It was the 282nd flight mission by a Long March carrier rocket.

·       The satellite, believed to be an optical imaging craft, is the latest in the Gaofen line of Chinese Earth observation missions.

Uses of Gaofen-11:

The satellite can be used for:

ü  Land survey

ü  Urban planning

ü   Road network design

ü  Agriculture

ü   Disaster relief.

ü   Belt and Road Initiative.

·       Since the Gaofen project began in 2010, China has gained an increasingly clearer view of the planet.

·       China had unveiled the BRI in 2013 with an aim to link Southeast Asia, Central Asia, the Gulf region, Africa and Europe with a network of land and sea routes. China launched the Gaofen project in 2010.

About Gaofen

·       China’s Gaofen satellites are part of the China High-Resolution Earth Observation System, or CHEOS.

·       Chinese officials say the CHEOS satellite fleet is a civilian-operated program comprising optical and radar imaging spacecraft and authorities have published high-resolution imagery taken by previous Gaofen satellites.

·       The launch of Gaofen 11 was China’s 22nd space launch of the year, equaling a record number of launches set by China in 2016.

·        In that year, Chinese rockets launched with satellites 22 times, but they suffered one failure and one partial failure.

·       All of China’s launches this year have been successful.
