China Puts New High resolution Satellite into Imagery Services

Опубликовано: 23 янв. 2017 г. China on Monday formally transferred its first Gaofen3 highresolution satellite from trial runs to imagery services. It now commands the highest resolution among microwave remote sensing satellites now in orbit. Launched into orbit in August last year, Gaofen3 has been testing its Cband polarimetric synthetic aperture radar imaging system which is capable of onemeter resolution. Imaging through microwaves has made it an allweather satellite. The trial runs have checked and verified its various systems and functions, including Earth observation in scanning widths of between 10 kilometers and 650 kilometers with resolutions of between one meter and 500 meters. During trial run in orbit, Gaofen3 has provided various users with close to 40, 000 images taken from 150 million square kilometers of ocean and land, said Tong Xudong, chief engineer for Gaofen Project. Apart from microwave, Gaofen3 also has 11 other imaging modes which facilitate i
