GF-3 SATELLITE

3 Satellites, SAR, 1 m Resolution, 12 Modes, Full Polarization, C-band

GF-3 (short for Gaofen-3) is composed of three satellites. The satellite is equipped a multi-polarized C-band Synthetic Aperture (SAR) at meter-level resolution. Its Imaging modes include spot mode, strip-map mode, and scan mode. GF-3 was launched on August 10, 2016, it is the first Chinese high-resolution SAR satellite to acquire multi-polarized SAR image with resolution of 1-500 m, and the imaging swath is 10-650 km depending on the varied imaging modes. GF-3 02 and 03 were successively launched on November 23, 2021, and April 7, 2022, they are GF-3's follow-on satellites and provided with very close parameters. The three satellites work as a constellation, doubling the collection and enhancing the revisit capacity.
