女娲星座






航天宏图"女娲星座"星座（也是（银河航天）INSAR编队星座）“航天宏图为实施“分布式干涉SAR高分辨率遥感卫星系统”项目，委托中国空间技术研究院对卫星系统提供论证、卫星系统方案设计和卫星工程监理服务；委托“银河航天”提供卫星研制、发射与在轨测试与交付、测运控系统等服务。“女娲星座”一期工程计划于2023年至2025年共发射38颗业务星，包括28颗雷达卫星组成的雷达遥感星座和10颗全色0.5米八谱段以及多光谱2米的光学卫星组成的光学遥感星座。2023年3月30日18时50分56秒，中国在太原卫星发射中心使用长征二号丁运载火箭，成功将宏图一号01组卫星发射升空。“女娲星座”首发卫星“中原一号（主卫星），鹤壁一、二、三号（三颗辅助卫星）”4颗高分辨率X波段合成孔径雷达卫星，是航天宏图“女娲星座”首发任务，是多星多基线分布式干涉雷达卫星系统、采用四星车轮式（Cartwheel）编队构型的多星分布式干涉合成孔径雷达卫星系统。主卫星位于中心，三颗辅助卫星均匀分布在轮毂上，这些在轨卫星还组成了地球历史上首个轮式卫星编队。是银河空间公司建造的中国干涉合成孔径雷达（InSAR）对地观测星座，由有源和无源 X 波段合成孔径雷达卫星组成。

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved  from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

    14 Oct 2020,  being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station.   The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station.  previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
