China uses first high-orbit remote sensing satellite
China’s first high-orbit remote sensing satellite, Gaofen-4, went into use after six months of inorbit testing, the State Administration of Science, Technology and Industry for National Defense announced.
Gaofen- 4 is China’s first geosynchronous orbit highdefinition optical imaging satellite and the world’s most sophisticated.
During the in- orbit test, Gaofen-4 has been used to collect images of flood-hit areas in south China and monitor fires that occurred in southwest China’s Sichuan province and in Russia.
China started the Gaofen project with the launch of Gaofen-1 in April 2013. It aims to launch seven high-definition observation satellites before 2020, designed for disaster prevention, surveillance of geological disasters and forest disasters and weather forecast.
