Four-channel VIS/NIR wide-view CCD camera carried by HJ-2A, with two parallel cameras, 720 km total swath, 16 m sub-satellite-point resolution, and four-day global coverage.

Sensor

WVC-2 is a wide-view VIS/NIR pushbroom CCD camera flown on the HJ-2A and HJ-2B Earth-observation missions.[1][2] It records four VIS/NIR channels covering 0.43-0.52, 0.52-0.60, 0.63-0.69 and 0.76-0.90 micrometre.[1] The instrument uses two parallel cameras: each camera has a 360 km swath, giving 720 km total swath, with 16 m resolution at the sub-satellite point and global coverage in four days.[1] Its utilisation period is 2020-2026 for the operational programme payload context.[1] Its demonstrated uses include vegetation-index mapping and optical time-series change detection, with broader high-resolution land-observation, natural-environment and disaster applications for the HJ-2A/HJ-2B payload context.[1][3]
