China has successfully launched a second GaoFen (GF)3 C-band satellite, used for remote sensing and Earth observation on November 22 at 23:45 UTC from the Jiuquan Satellite Launch Center (JSLC).
The GaoFen-3 satellite is equipped with a C-band Synthetic Aperture Radar (SAR) and a data transmission system and utilizes Control Moment Gyros (CMGs) for orientation in space. The satellite offers a multi-polarization imaging mode with the highest resolution of 1 meter.
GaoFen 3-2 is the follow-up satellite and will work with the on-orbit Gaofen-3 satellite, launched in 2016 focusing on ocean observation. The GF3 satellite series offers 12 different modes of imaging and multi-polarization methods (HH) (HV) (W) (VH). The first launch of the GaoFen (“high resolution”) series satellites took place in 2013. After that, 22 more GaoFen satellites entered service, with the latest installment being the Gaofen-5-2 mission in September 2021.
HEAD has further expanded the choice of satellite sensors in their product portfolio by adding this new radar GF3-2 satellite. The current satellite portfolio consists of 47 satellites offering satellite imagery including SAR, HyperSpectral, Nighttime imagery, and video from space.
