任务简介
CHORUS 是 MDA 的下一代地球观测星座，由两颗雷达卫星（C 波段 SAR 和 X 波段 SAR）组成，运行在倾角 53.5 度、高度 600 公里的 LEO 轨道上，其中 X 波段卫星落后 C 波段卫星 60 分钟。作为一个多传感器协同星座，CHORUS 将整合多样且独特的影像和数据源，提供更高水平的近实时洞察和创新的地球观测服务。运行在独特的中倾角轨道上，CHORUS 能够昼夜成像，不受天气条件影响，每天可覆盖高达 95% 的区域。从行业领先的 700 公里宽成像幅宽到亚米级高分辨率，CHORUS 将在单次任务中提供市场上最广泛且无与伦比的地球观测雷达成像能力。

CHORUS is MDA's next generation Earth observation constellation, consisting of 2 radar satellites (C-band SAR and X-band SAR), in a 53.5 degree 600 km altitude LEO, with the X-band trailing the C-band by 60 minutes. A collaborative multi-sensor constellation, CHORUS will bring together diverse and unique imagery and data sources and provide a new level of near real-time insight and innovative Earth observation services. Operating in a unique mid-inclination orbit, CHORUS will be able to image day or night, regardless of weather conditions, with daily access of up to 95% of the coverage area. From an industry-leading 700km-wide imaging swath down to sub-metre high resolution, CHORUS will provide the most extensive and unrivalled Earth observation radar imaging capacity available on the market in a single mission.
