China plans to build a comprehensive earth observation system in next 10 years. This system will  integrate use of air, space and ground based technology, including drones, satellites and GPS systems to serve economic and social development sectors.

The Beidou system, operational in China, has 16 navigation satellites providing GPS services across Asia-Pacific region. China plans to increase this number to 30 satellites by 2020 to make it a comprehensive GPS which it hopes to market widely in the region including India. According to the government officials, the quality of the pictures and data taken by the satellites will be greatly improved.

Luan Enjie, an academic at the Chinese Academy of Engineering, said that the launching of Gaofen-1 and Gaofen-2 satellites means the country has entered a new era of independently developing high-definition satellites and the end of the dependency on foreign satellites.
