China Launches Gaofen-12 (02)

China launched Gaofen-12 (02) on 31 March 2021 into a sun-synchronous orbit, adding another likely SAR imaging satellite to the expanding Gaofen constellation.

31 Mar 2021: China launched the Gaofen-12 (02) (likely a SAR imagery satellite) on a Long March 4C from Jiuquan, northwest China. The country’s Gaofen constellation continues to grow at an impressive rate, having launched 8x Gaofen in 2020. See VIDEO.

– The Gaofen-12 (02) satellite was sent into a 594 x 600 kilometer sun-synchronous orbit, according to U.S. satellite tracking. The first Gaofen-12 was launched into a similar initial orbit in December 2019. View orbit.

– The Gaofen-12 (02) satellite is nominally part of the civilian China High-resolution Earth Observation System (CHEOS). Chinese media state that the satellite will be used in land surveys, urban planning, road network design and crop yield estimation, as well as disaster relief.

– CHEOS was initiated in 2010 to provide all-weather/day coverage with synthetic aperture radar and EO satellites.

– Gaofen 12 and 12-2 are equipped with high-resolution capability via a microwave remote sensing system (SAR), with ground resolution estimated up to the sub-meter level. It is possibly a civilian version of the Yaogan 29 type satellite.

Resolution capabilities and other information has been published for lower numbered Gaofen series satellites. However information for Gaofen satellites numbered 8 and above has not been openly released, suggesting the satellites are for national defense purposes.
