    "The China Commercial Remote-sensing Satellite System (CCRSS) will be able to collect data on 328 bands offering very high resolution of up to 15 metres, according to the researchers from the Institute of Remote Sensing and Digital Earth in Beijing. This means each pixel in the image measures 15 metres squared.

    Hyperspectral research efforts have been going on in China for several decades, having begun at the start of the 1970s, the team said in a presentation.

    The technology was tested extensively and improved over time on aircraft-based platforms, before researchers shifted their attention to devices in space.

    The first satellite-based hyperspectral camera, called the CMODIS, was installed on Shenzhou-3, an unmanned spacecraft that China launched in 2002.

    The camera was fairly primitive with just 34 spectral bands and resolution as low as 500 metres, but it was soon replaced as Chinese technology in this area developed at a fast clip.

    By 2008 the small satellite constellation known as HJ-1 was able to scan 115 bands with resolution of 100 metres, according to the researchers.

    But as these developments and sensors all took place in equipment destined for the civilian sector, many suspect the cameras used by China’s military can perform significantly better."
