On April 18th, IT House reported that the Long March 2D carrier rocket successfully launched, accurately placing the GF-3 01 satellite into its designated orbit. According to CCTV News, the satellite carries a self-developed four-dimensional wide-field electronic component by China Electronics Technology Group Corporation (CETC), featuring chips. It has already been successfully powered on and transmitted its first satellite image. The initial image is clear, rich in detail, and accurate in color.

Reportedly, this four-dimensional wide-field electronic component is China’s first application of a nine-band TDICCD product, boasting high transmission function, large dynamic range, and strong resistance to glare. In addition to the traditional panchromatic, red, green, blue, and near-infrared bands, the imaging component has added four new bands including coastal aerosols, yellow, and red edge, enabling the satellite to achieve a high resolution of 0.5 meters, a wide imaging capability of over 130 kilometers, and nine-band imaging capability.

After the satellite operates in orbit, this component can comprehensively utilize high-resolution wide-field imaging methods to acquire high-resolution image data, which can be used for various quantitative applications such as cloud and fog removal, land classification, and vegetation detection. The image data will effectively support applications in China’s fields of national land resource survey, urban management, environmental protection, disaster prevention, and reduction.

China Electronics Technology Group Corporation continues to advance the series development of multispectral TDICCD products, having established a complete supply chain from design, manufacturing, packaging to testing. This provides solid technical support for independent innovation in China’s aerospace remote sensing imaging field, constituting key core products.
