Abstract

GEZGİN-2 is the image processing subsystem of RASAT, an earth-observing small satellite which has been developed, built and qualified by TÜBİTAK-UZAY for a LEO mission. GEZGİN-2 is responsible for real-time compression of multi-spectral images acquired by the push-broom imagers of RASAT, before being transferred to the Solid State Data Recorders on-board the satellite. By applying compression to image data prior to recording, on-board storage space and downlink communication bandwidth of RASAT is more efficiently utilized. GEZGİN-2 realizes its image processing tasks through a fully integrated application specific digital architecture, delivering a processing rate of 55Mbps and consuming 6 Watts. As all subsystems of RASAT, GEZGİN-2 has been implemented with commercial-off-the-shelf (COTS) components but qualified for its LEO mission through thermal vacuum cycling and vibrations tests compliant to ESA specifications. GEZGİN-2 has been successfully integrated on RASAT in year 2010 and is ready for launch.

GEZGİN-2: RASAT的图像处理子系统

GEZGİN-2是RASAT的图像处理子系统，这是一颗地球观测小卫星，由TÜBİTAK-UZAY开发、建造并获得LEO任务资格。GEZGİN-2负责实时压缩由RASAT的推扫帚成像仪获得的多光谱图像，然后将其传输到卫星上的固态数据记录器。通过在记录之前对图像数据进行压缩，可以更有效地利用RASAT的板载存储空间和下行通信带宽。GEZGİN-2通过完全集成的应用特定数字架构实现其图像处理任务，提供55Mbps的处理速率和6瓦的功耗。与RASAT的所有子系统一样，GEZGİN-2已使用商用现货(COTS)组件实施，但通过符合ESA规范的热真空循环和振动测试，符合LEO任务的要求。GEZGİN-2已于2010年成功集成到RASAT上，并准备发射。
