  • GF-2 (Gaofen-2) is the second high resolution imaging satellite of China high resolution earth observation system (CHEOS) and it is the first civilian high resolution imager with Ground sample distance (GSD) under 1m in China. The two 1m/4m cameras represent a breakthrough in comparison with the previous GF-1 camera. Recent advances in small relative aperture optics system design, vibration reduction, and high accuracy thermal control make it possible for this camera work perfect with high resolution, lihgtweight and high image quality performance. The in-orbit commissioning demonstrates that the performance of the cameras meets all the design requirements. The components of 1m/4m camera, the novel techniques adopted and in-orbit commissioning results are illustrated.
