The 2 CCD cameras adopt the same design, and placed symmetrically at nadir and split the field of view and observe in parallel and realize imagery of 700 km swath, 30 m resolution and 4 spectral bands. The hyperspectral imager enables HJ-1A 50 km swath, 100m resolution and 110~128 bands and ±30° oblique viewing angle. The infrared camera enables HJ-1B 720 km swath, 150/300 m resolution and 4 spectral bands.
